Здравствуйте!
Может кто-нибудь подсказать, как апгрейдить vrds 10?
Если у кого-то есть схемотехника на аппарат, можно ли скинуть?
Заранее спасибо!

I have found a lot discussions on the philips units, but what about the VRDS-units of TEAC ? Have they alle the same drive / chipsset inside or are there differences ? Anyone listen experiences ?

Hi
It depends on your interest
Best drive / mechanics: VRDS 10, 20 and 25
Best price probably the VRDS 8, 9 or T1. Both have a derived drive from the 10, it is not as rock solid and to my experience you van get as far as with a 10. You have to work on them, all.
I do not have detailed info on the pickup units. All play CDR by the way...
They all use about the same chipset. Analogue parts differ though
Do not buy a 9 if you go for mods, the 9 is a disaster to work on due to the way it is assembled
I have 10 running for about 8 years now, no problems, though some units are somewhat sensitive. Firmware sometimes messes up the things too
regards
Blitz
Interesting...I was more thinking wether the VRDS 10 has the same drive / digital chipset as the VRDS 25. I understand from you that this is the case, right ? So, there is no need to look for a much more expensive 25 when I only want the best drive around.
tbla
the best from teac is the drive used in p1 and p2 and the old x1.
spectral use it in there top player.
and this is the newest
edit, wadia used this very expensive drive in there 7/9 combination.

these drives are not alike...
wrds 10 is a 4,x drive with analog servo
and the wrds 25 is a 3,2 drive with digital servo
and the best is from the x1 and p2 with a (i think) 2,x drive - very different and much more expensive...

Hi Tbla,
why not you ask at Copland,
Bw the copland company use the VRDS system, only change the final
analol stage.

these days they only use sony drives...but years ago in there top of the line player, they used the 4,x drive as in teac wrds10 and also one of the krells.
in some ways the old copland was a nice player - after heavy modding...
bambadoo
Copland has modded their VRDS-drive for their players (that use VRDS transport. (CDA288, CDA277). This is according to Ole M§ѕller founder and constructor of Copland.
BTW. I use Copland CDA288X moddes with XO2 clock, Mcap Supreme silver/oil caps, silver wire, plastic removal in caps etc. It plays wonderful. I have had the TEAC VRDS 10 also.
But now the copland is used as a transport.

They did something with the servo controlling the VRDS system.
I was told this by the Norwegian Importer who happens to know Ole M§ѕller quite well.
Some modifications were done regarding the noise supplied by the drive itself. (Spinup and spindown time) and also when you turn off the unit.
One minor "fault" in the Teac drives ( VRDS 10), was that when you press "stop" on the player the engine that controls the drive still spins, this doesnt happen in the Copland players.
This is more a bug in Teac than a fix in Copland.
But one of the reasons Copland went for Sony drives in their players was that they were more "easy" to work with and implement with coplands own dacs, servos and PSUs. More "Tweakable".
However the VRDS system outperforms the Sony drives in almost all aspects.

Hi Guys,
I must say, that tbla is right!
I happen to know almost all the VRDS transports, and all the transports I saw uses the KSS-xxx SONY pickup unit!
The P70 is the most expensive one and the best Ive ever heard,
I must say that, like Guido said, if you take care of the servo of the 25X transport and again like tbla said, take good care of the poweer supply and youll be having one of the best transport moneyy can buy!
To tell you the truth, I prefer the 25X transport with its great servo system, its (almost) the same, after mods, sound wise, as the expensive P70 that cost EURO 8000,= A friend of mine uses this transport and it is a real beauty! Look at and youll understand what I mean.
The P-700 transport uses the same transport ans the 25X BUT WITHOUT THE SERVO! Again, powersupply and clocks must be modified otherwise youll never get what its capable of!
Best regards,
Audiofanatic
P-70 mechanism!

Hi,

I also have a 25x.One of the reasons I bought it was that it was future proof in that you could use it as a great transport with an external DAC.I remember very clearly that when I auditioned it although quite good as a standalone CDP for its price it was much better than much more expensive players as a transport.In fact it was as good as transports costing over 4000 euro.
It benefits a lot from the right kind of vibration isolation despit its good build.

Hi Blitz,
If you dont mind about the size, go for the 25!
If you want a small case grap the P-700.
Both are great! The only problem is, I never opened a 25, only a 25X.
Maybe an other forum member has or had one and know the player/transport!
So again, with servo is better than without!
If size matter, take the P-700!

They are cheaper all right, but as I said, the sony drive units seemed easier to work with for Ole M§ѕller.
Have TEAC stopped supplying VRDS drives for Wadia also?
BTW. Krell has also used VRDS drives in their earlier designs.

Unfortunately, I dont know.
I never had a 25 on the bench, so I can not tell!
I know that my 25X is allmost as good as the P-70 I know them both!

P.S. I think that the 25 has no digital servo in the transport motor, but dont know that for shure.

Hi
I bought 2nd hand a Copland 288 and it has the teac drive in it.
I already changed the cheapish internal clock for a an XO3 clock with much less jitter and the sound became more solid, quiet and transparent (more space)
But if I understand you all well, the teac needs more mods to truly shine?
Can you elaborate more on this?
what exactly can i do?
thanx
Kyrill
bambadoo
If you want your 288 to really shine, swap a couple og 0.47uf caps in the analog section to mcap supreme silver/oil.
I have made a post on this, the pictures speaks for themselves. The language is in Norwegian.
BTW. What is the price of a used TEAC p-700 drive?
And what VRDS mechanism is in it?
I can get one for 160$
Best Regards
kyrill
thanks
I payed 1100 euro for the copland september last year.

Hi Bambadoo,
If you have the chance to buy the P-700, dont hessitate!
BUY THE TRANSPORT!
its better than the Copland unit. the Copland uses a KSS -240A ?
And the P-700 uses a KSS-151A this laserunit is much better and the transport of the P-700 is much better than the Copland.
You must modify the unit in order to get the most out of it.
I have one and I have the Kwak Clock installed in it, PSU is new and all caps are Oscons and BGs. Silver wired!
Its better than the WADIA 21 !!!!!!!!!!!!!!!!
Best regards,
Audiofanatic
P.S. dont use a SP/DIF output transformer make a Kwak one. Ask Elso about this.
bambadoo
Thanks for the information. I have a modified audionote dac that I like really much, and its a shame to use the copland only as a transport.
Do you know when the unit (p-700) was produced? And what the price was?
Its a bit difficult to find information of it.

Hi Bambadoo,
Check the inside of the unit, look at the pcb and find (somwhere) a prod. date, and one or two years to that date.
If you dont want the P-700 transport, I know somone who might want the Transport. Be carefull not to buy one with a weak Laser unit!!!
BTW. the pics of the copland shows that the transport inside looks like a T1/ VRDS 7 transport, the VRDS10,25,25X etc has a better transport.
Best regards,
Audiofanatic
P.S. August,
mods done on my P-700 and my VRDS 25X are really simple.
PSU, SERVO, CABLES/CONNECTORS, NEW CASE ALA WADIA, BGs
AND OsCONs Where possible.

Hi,
I sure will tell you guys what I did. But some guys on the forum, Dutch guys, will kill me if I tell what I did to the servo.
So for the standard mods, Ill get back to you within a few days. For the Servo mods, Im sorry, I can not tell you guys, cause the mods to the servo is done by a friend and he will not tell about it, I dont know a thing about Digital, Analogue is my thing. Why dont you ask the Digital wonders on the forum, for mods on the digital part.
Best regards,

Age dont say anything!
Mine was also 10x used but the laserunit was not good!
Dont buy if you are not sure or are not willing to buy and install a new laserunit KSS-151A its expensive!

Hi Arne
How can I find out which (SONY?) laserunit I need for my Copland?
I seemt to have the latest cd 288 and hear rumours that it has the better TEAC 25 transport as oppose to the VDRS 10?
: )

The copland cda288 uses the kss -240a
The vrds mechanism in the copland is the cmk 4. Not the same as in vrds 10 or vrds 25.

But I see you as well Arne made pictures from inside. So I will look inside to see if I can see white sticker as well.
Will it also be so easy to find out which TEAC transport the player utililises?

Guido & all,
I really would like to understand the VRDS series composition better..
VRDS 20 is a souped up VRDS 10 - both are transport + DAC
VRDS T1 is the "transport only" version of the VRDS 10 it seems, right ?
all of these originated around 1993
Now the VRDS 25 is of newer date and theres a special version, the VRDS 25x which features some "selected" components
From some sources on the web I do read that the VRDS P70 model is the transport-only version of the VRDS 25
now what about the VRDS X1, VRDS X2, VRDS T2 and VRDS P30 ? how do these stack up against the rest ? I know in the US a part of these players/transports were marketed under the high end "Esoteric Audio" brand..
Also it seems that the VRDS 7 is one to avoid, some posters claim it has "plastic" platter. What about the others - do they have metal platter ?
any input appreciated

Hi
The T1 uses the transport of the VRDS 8/9. This is a cost down of the transport used in the 10/20/25.
Straight from the box the T1 sounds beter than a 10, dont ask me why, but the 8/9 and T1 show more mechanical failures.

Crossy
Guido,
many thanx - much appreciated..
looks like the actual composition of the VRDS drive mechanisms of the P30, the P70 and the X1 or X2 still remain a "mystery" ..

Im glad this thread has come back to life. I have an Esoteric P-700 which Ive been using as my main transport for a while, and Im interested in mods -- all Ive done is replaced the RCA out with a BNC. If anyone can shed some light on that digital servo improvement mentioned above, let me know.
Also, Guido et al: How much trouble is it to put a new clock in this thing? Ive got one of your clocks in my DAC (a PCM63K unit); Im sure youd argue that its worth reclocking this transport, too, but how accessible is it?
Third: How good is the digital output transformer/pre-transformer padding on this thing?
Finally: Big flaw with VDRS players is that they have high mechanical noise -- i.e. you can hear them spinning if youre within a couple metres of them (assuming theres a quiet passage on). I HAVE done a lot of mods to this end - - damping sheets inside, Sorbothene, etc, but its still not silent. Thoughts?

I did a Tent XO3 and XO power supply in a P700 a few months ago very sucessfull, space is a problem the XO3 had to go under the main board mounted upside down attached to the main boards soldered side and the supply on its side near the mains input. The results were more relaxed sound (not so edgy) and bigger more 3D sound stage, well worth the effort. (and do use the XO3s spdif output, better than the Teacs spdif )
Compared to my own Teac VRDS-T1 (with XO3 & XOsupply) the T1 just edges ahead of the P-700 (with XO3&XOsupply)
Cheers George
Crossy
I got a used P-700 from France .. not having it before me yet.
First of all, Im not really versed in doing these moddings myself (lacking the highdensity-soldiering capability and the proper T&M gear) but I think I can understand the backgrounds well enough.
Conceptually, in some settings I could think about these low jitter clocks as "overkill". If your external DAC does resampling, it should kill any jitter with it (such as the Apogee Rosetta wich I plan to obtain) . So improving the motor stage and the PSU might appear more straightforward than outfitting the P-700 with an ultra stable oscillator.
There is even another potential oddity here if one uses an external DAC that does resampling: I do know that many of the VRDS series - definitely the VRDS 25 - use resampling internally already - in a rather tricky way to eliminate jitter. Now if this design is being used in the P-700 as well (which I dont know yet) another resampling stage in an external DAC might not be advisable.. (the signal would be resampled twice)
as always .. you solve one issue and a whole lot of new questions appear..

"Overkill" hardly, Ive had two Teac VRDS-T1s side by side one fitted with the XO3 and XOsupply the other standard. both going into a very good dac that had 2x coax inputs switchable.
Both transports same disc switched between the two and the difference is night and day, the modded one has more a relaxed presentation and a sound stage that is much larger and 3d. the non modded one collapses the sound back into the speakers and brightens/thins the sound out.
Cheers George
dougigs
George, slightly OT buy how do you handle the input switching on that DAC?
Ive got one of mine rigged to switch between two SPDIF inputs, using two relays positioned as close to the BNC connectors (and the PCB input) as possible. Still, I worry that this is a messy way to do things. Any advice on switching schemes?
georgehifi
Its the Teac D500 the mate of the P500 that a friend owns, not sure how they do it, but its got 2x toslinks and 2x rca coax so you can switch between 4 x transport if you like from the front pannel select button from memory (maybe relays).
Cheers George
dougigs
Yeah, Ive got a similar switching scheme in a D-700 DAC, which I use in my kitchen setup (it came with the transport). It uses the same switching scheme. Its a row of relays... I actually worry about the lead lengths on it, esp. given their proximity to the power supply. Thats my concern: How do you implement an input-switching scheme thats not going to act as a big antenna?
Some people here have suggested air-wiring the zobel components straight onto the BNC leads to keep things crisp... In a switched setup, do we suggest having redundant sets of passive components wired onto the relay outputs, or just one set close to the input transformer?
dubkarma
A dumb question perhaps, but...
how does one tell a VRDS 25 and a VRDS 25X apart?
Does the X version have "VRDS 25X" printed/silk-screened on the face plate?
The reason I ask is that I have the opportunity to purchase a VRDS 25. The vendor is "almost certain" that its a 25X, but also admits that it says "VRDS 25" (no X) on both front and back plates.
Date of manufacture is December 1995, which strikes me as too early for the X version, which I understood was manufactured only from 1997 or 1998.
If anyone could suggest a fool-proof test for distinguishing a VRDS 25X from a "plain" VRDS 25, Id be most grateful.
I did phone the Teac parts depot in the U.S. and confirmed that the 25 and the 25X have separate service manuals, so I assume that there are at least some electronic differences.
Thanks in advance,
Joel Tatelman.
desjet
Hi,
the 25X model have digital inputs (you can use it as a dac), the 25 not. The schematics are nearly identical.
25X: The Teac logo on the face plate is engraved
25: The Teac Logo is plastic

resampling does not kill but only attenuate the incomming jitter. Like with any attenuator, less in = less out
Lower jitter from the drive is always benneficial, I yet have to find a DAC that is fully insensitive for incomming jitter.

Dear all members,
I read that you all know Teac vrds and Im searching for information.
I have a vrds P500 on a Cayin da2 DAC (6922 valves).
I have an opportunity on a vrds 9 for around 330 ©¤, almost new.
Is it worth upgrading from a P500 to vrds 9 drive ?
Or should I get a vrds 10se or 25x ?
Thank you !

Just wanted to throw in a "satisfied customer" report.
I purchased a "transport upgrade kit" for my VRDS 25 from AES-Audiotuning in Germany (). I asked a lot of questions before buying and got patient answers with many colour photos in reply. Very good customer relations.
The kit consisted of Black Gate caps for the power supply, an XO Clock 3 and XO Clock 3 power supply, and a digital output board with XLR (AES-EBU) and BNC (SPDIF) output connectors (RCA-BNC and XLR-RCA combinations also available).
The parts were well packaged and made it from Germany to Canada in about seven business days for only US$15.00.
I had a local technician install the parts.
Distinct improvement in clarity and detail but at the same time "smoother." Better localization of instruments and voices.
Currently used with a stock Benchmark DAC1. Will soon be trying out a Lavry Black DA10, so Id be grateful for any comments of listmembers who have compared these two DACs.
Regards,
Joel.

Cannot think of anything one may do apart from upgrading the servo power supply with the usual arsenal .i.e better regulators (LT series) or discrete Jung type a la ALW, better caps/bypassed etc.Otherwise you get into the realm of tinkering with the servo icЁfs etc which would be way beyond even some gurus here.

Thanks!
I have not tried but it looks possible to me.

I am so excited to come across the information on the Teac transports here. My P-500 is having a problem with laser-pickup. I want to replace it and have the unit modified too. Can somebody give me advice please? Thanks.

I purchased a "transport upgrade kit" for my VRDS 25 from AES-Audiotuning in Germany (). I asked a lot of questions before buying and got patient answers with many colour photos in reply. Very good customer relations.
The kit consisted of Black Gate caps for the power supply, an XO Clock 3 and XO Clock 3 power supply, and a digital output board with XLR (AES-EBU) and BNC (SPDIF) output connectors (RCA-BNC and XLR-RCA combinations also available).
The parts were well packaged and made it from Germany to Canada in about seven business days for only US$15.00.
I had a local technician install the parts.
Distinct improvement in clarity and detail but at the same time "smoother." Better localization of instruments and voices.
Currently used with a stock Benchmark DAC1. Will soon be trying out a Lavry Black DA10, so Id be grateful for any comments of listmembers who have compared these two DACs.
Regards,
Joel.
More updates on this?
I also have a dac similar to the benchmark and looking to buy a VRDS transport...
dubkarma
Telstar,
Updates? Well, Im still using the VRDS-25 modified as a transport with parts from AES-Audiotuning; still using it with a Benchmark DAC1; still satisfied with the performance. As a matter of fact, its not far off in performance from my Teac/Esoteric P-70 transport. The crucial difference is that the P-70 has a word-clock input so that it can be slaved to a DAC that has a word-clock output.
In addition, I recently purchased a VRDS-25X. This time I may mod the entire unit and not use an external DAC. Well see.
Regards,
Joel.

My DAC is the TwinDAC+ and I think it is similar to the latest version of the benchmark, but has only one digital rca input and one usb (perfect for me).
Im considering purchasing a sacd transport but Im afraid that with vrds mechanic there is only the expensive esoteric models.
Im considering the DV50s (I know it doesnt have a vrds mechanic) to mod in the clock/fuse parts.
For redbook playback Im going with computer-based playback, so my interest for cd-spinner would be only SACD and DVD-A.
I remember that some Wadia sacd players or transports have teac vrds mechanic but I cannot find which ones.

Which are the essential mods to be done to a VRDS 25 or 10SE for use as a transport?
clock with its psu, then?
georgehifi
Here is a pic of the Tentlabs XO3 and XO supply mounted under the main digital decoder board (board to go on top) is is the best position for it as all leads are kept to a minimum.
I have done close to ten now Vrds-T1 Vrds-10 Vrds10se and Vrds-25s
The difference in sound is very noticable with all models, more extension top and bottom more grunt to the bottom end, yet tighter, top end is more extened and floats out from the speakers, instead of being squeezed out of the tweeter, overhaul a more relaxed presentation yet more dynamic.
Cheers George

Thanks, Ill use for sure XO3 and XO supply, but i was thinking also to upgrade the digital outputs since the main use of the 10SE that Im buying is as transport.
Any more useful mods? I have about 400©¤ budget, covering also labour.
Besides, I wrote to Guido Tent and Ill buy the components from him
georgehifi
When you instal the XO3 make sure you use its better spdif output, it sound better that the Teacs 10SEs.
Thats it youll have a word class transport that will be near impossible to beat.

Yes the XO3 has a spidf output, the 10, 10se and 25 have the same mech and laser the T1 is a little cheaper in its mech and laser but still very good. Yes Sony decoders.

Tentlabs power supply has very good galvanic isolation because he uses chokes in it as well, stick to it.
(galvanic isolation ) the noise of the xtal itself isnt fed back through the power supply into the rest of the system. I think this is what Guido said to me one day.

Hi
It depends on your interest
Best drive / mechanics: VRDS 10, 20 and 25
Best price probably the VRDS 8, 9 or T1. Both have a derived drive from the 10, it is not as rock solid and to my experience you van get as far as with a 10. You have to work on them, all.
I do not have detailed info on the pickup units. All play CDR by the way...
They all use about the same chipset. Analogue parts differ though
Do not buy a 9 if you go for mods, the 9 is a disaster to work on due to the way it is assembled
I have 10 running for about 8 years now, no problems, though some units are somewhat sensitive. Firmware sometimes messes up the things too
regards
Blitz
Interesting...I was more thinking wether the VRDS 10 has the same drive / digital chipset as the VRDS 25. I understand from you that this is the case, right ? So, there is no need to look for a much more expensive 25 when I only want the best drive around.
tbla
the best from teac is the drive used in p1 and p2 and the old x1.
spectral use it in there top player.
and this is the newest
edit, wadia used this very expensive drive in there 7/9 combination.
tbla

these drives are not alike...
wrds 10 is a 4,x drive with analog servo
and the wrds 25 is a 3,2 drive with digital servo
and the best is from the x1 and p2 with a (i think) 2,x drive - very different and much more expensive...

Bw the copland company use the VRDS system, only change the final

these days they only use sony drives...but years ago in there top of the line player, they used the 4,x drive as in teac wrds10 and also one of the krells.
in some ways the old copland was a nice player - after heavy modding...
bambadoo
Copland has modded their VRDS-drive for their players (that use VRDS transport. (CDA288, CDA277). This is according to Ole M§ѕller founder and constructor of Copland.
BTW. I use Copland CDA288X moddes with XO2 clock, Mcap Supreme silver/oil caps, silver wire, plastic removal in caps etc. It plays wonderful. I have had the TEAC VRDS 10 also.
But now the copland is used as a transport.

They did something with the servo controlling the VRDS system.
I was told this by the Norwegian Importer who happens to know Ole M§ѕller quite well.
Some modifications were done regarding the noise supplied by the drive itself. (Spinup and spindown time) and also when you turn off the unit.
One minor "fault" in the Teac drives ( VRDS 10), was that when you press "stop" on the player the engine that controls the drive still spins, this doesnt happen in the Copland players.
This is more a bug in Teac than a fix in Copland.
But one of the reasons Copland went for Sony drives in their players was that they were more "easy" to work with and implement with coplands own dacs, servos and PSUs. More "Tweakable".
However the VRDS system outperforms the Sony drives in almost all aspects.
Audiofanatic
Hi Guys,
I must say, that tbla is right!
I happen to know almost all the VRDS transports, and all the transports I saw uses the KSS-xxx SONY pickup unit!
The P70 is the most expensive one and the best Ive ever heard,
I must say that, like Guido said, if you take care of the servo of the 25X transport and again like tbla said, take good care of the poweer supply and youll be having one of the best transport moneyy can buy!
To tell you the truth, I prefer the 25X transport with its great servo system, its (almost) the same, after mods, sound wise, as the expensive P70 that cost EURO 8000,= A friend of mine uses this transport and it is a real beauty! Look at and youll understand what I mean.
The P-700 transport uses the same transport ans the 25X BUT WITHOUT THE SERVO! Again, powersupply and clocks must be modified otherwise youll never get what its capable of!
Best regards,
Audiofanatic
P-70 mechanism!

Hi,

I also have a 25x.One of the reasons I bought it was that it was future proof in that you could use it as a great transport with an external DAC.I remember very clearly that when I auditioned it although quite good as a standalone CDP for its price it was much better than much more expensive players as a transport.In fact it was as good as transports costing over 4000 euro.
It benefits a lot from the right kind of vibration isolation despit its good build.

Hi Blitz,
If you dont mind about the size, go for the 25!
If you want a small case grap the P-700.
Both are great! The only problem is, I never opened a 25, only a 25X.
Maybe an other forum member has or had one and know the player/transport!
So again, with servo is better than without!
If size matter, take the P-700!

Have TEAC stopped supplying VRDS drives for Wadia also?

Hi
I bought 2nd hand a Copland 288 and it has the teac drive in it.
I already changed the cheapish internal clock for a an XO3 clock with much less jitter and the sound became more solid, quiet and transparent (more space)
But if I understand you all well, the teac needs more mods to truly shine?
Can you elaborate more on this?
what exactly can i do?
thanx
Kyrill

If you want your 288 to really shine, swap a couple og 0.47uf caps in the analog section to mcap supreme silver/oil.
I have made a post on this, the pictures speaks for themselves. The language is in Norwegian.
BTW. What is the price of a used TEAC p-700 drive?
And what VRDS mechanism is in it?
I can get one for 160$

Hi Bambadoo,
If you have the chance to buy the P-700, dont hessitate!
BUY THE TRANSPORT!
its better than the Copland unit. the Copland uses a KSS -240A ?
And the P-700 uses a KSS-151A this laserunit is much better and the transport of the P-700 is much better than the Copland.
You must modify the unit in order to get the most out of it.
I have one and I have the Kwak Clock installed in it, PSU is new and all caps are Oscons and BGs. Silver wired!
Its better than the WADIA 21 !!!!!!!!!!!!!!!!
Best regards,
Audiofanatic
P.S. dont use a SP/DIF output transformer make a Kwak one. Ask Elso about this.
bambadoo
Thanks for the information. I have a modified audionote dac that I like really much, and its a shame to use the copland only as a transport.
Do you know when the unit (p-700) was produced? And what the price was?
Its a bit difficult to find information of it.

Hi Bambadoo,
Check the inside of the unit, look at the pcb and find (somwhere) a prod. date, and one or two years to that date.
If you dont want the P-700 transport, I know somone who might want the Transport. Be carefull not to buy one with a weak Laser unit!!!
BTW. the pics of the copland shows that the transport inside looks like a T1/ VRDS 7 transport, the VRDS10,25,25X etc has a better transport.
Best regards,

P.S. August,
mods done on my P-700 and my VRDS 25X are really simple.

Hi,
I sure will tell you guys what I did. But some guys on the forum, Dutch guys, will kill me if I tell what I did to the servo.
So for the standard mods, Ill get back to you within a few days. For the Servo mods, Im sorry, I can not tell you guys, cause the mods to the servo is done by a friend and he will not tell about it, I dont know a thing about Digital, Analogue is my thing. Why dont you ask the Digital wonders on the forum, for mods on the digital part.

I seemt to have the latest cd 288 and hear rumours that it has the better TEAC 25 transport as oppose to the VDRS 10?
: )

The copland cda288 uses the kss -240a
The vrds mechanism in the copland is the cmk 4. Not the same as in vrds 10 or vrds 25.

bambadoo
thanks
But I see you as well Arne made pictures from inside. So I will look inside to see if I can see white sticker as well.
Will it also be so easy to find out which TEAC transport the player utililises?

What a pity...I taught the Copland had a good type...

Hello,
could somebody tell me wich laserunit I must buy for a VRDS 10 SE please ?
I think that its this one but Im not sure ?
Thanks

Guido & all,
I really would like to understand the VRDS series composition better..
VRDS 20 is a souped up VRDS 10 - both are transport + DAC
VRDS T1 is the "transport only" version of the VRDS 10 it seems, right ?
all of these originated around 1993
Now the VRDS 25 is of newer date and theres a special version, the VRDS 25x which features some "selected" components
From some sources on the web I do read that the VRDS P70 model is the transport-only version of the VRDS 25
now what about the VRDS X1, VRDS X2, VRDS T2 and VRDS P30 ? how do these stack up against the rest ? I know in the US a part of these players/transports were marketed under the high end "Esoteric Audio" brand..
Also it seems that the VRDS 7 is one to avoid, some posters claim it has "plastic" platter. What about the others - do they have metal platter ?
any input appreciated

Hi
The T1 uses the transport of the VRDS 8/9. This is a cost down of the transport used in the 10/20/25.
Straight from the box the T1 sounds beter than a 10, dont ask me why, but the 8/9 and T1 show more mechanical failures.

Crossy
Guido,
many thanx - much appreciated..
looks like the actual composition of the VRDS drive mechanisms of the P30, the P70 and the X1 or X2 still remain a "mystery" ..

Im glad this thread has come back to life. I have an Esoteric P-700 which Ive been using as my main transport for a while, and Im interested in mods -- all Ive done is replaced the RCA out with a BNC. If anyone can shed some light on that digital servo improvement mentioned above, let me know.
Also, Guido et al: How much trouble is it to put a new clock in this thing? Ive got one of your clocks in my DAC (a PCM63K unit); Im sure youd argue that its worth reclocking this transport, too, but how accessible is it?
Third: How good is the digital output transformer/pre-transformer padding on this thing?
Finally: Big flaw with VDRS players is that they have high mechanical noise -- i.e. you can hear them spinning if youre within a couple metres of them (assuming theres a quiet passage on). I HAVE done a lot of mods to this end - - damping sheets inside, Sorbothene, etc, but its still not silent. Thoughts?

I did a Tent XO3 and XO power supply in a P700 a few months ago very sucessfull, space is a problem the XO3 had to go under the main board mounted upside down attached to the main boards soldered side and the supply on its side near the mains input. The results were more relaxed sound (not so edgy) and bigger more 3D sound stage, well worth the effort. (and do use the XO3s spdif output, better than the Teacs spdif )
Compared to my own Teac VRDS-T1 (with XO3 & XOsupply) the T1 just edges ahead of the P-700 (with XO3&XOsupply)
Cheers George
Crossy
I got a used P-700 from France .. not having it before me yet.
First of all, Im not really versed in doing these moddings myself (lacking the highdensity-soldiering capability and the proper T&M gear) but I think I can understand the backgrounds well enough.
Conceptually, in some settings I could think about these low jitter clocks as "overkill". If your external DAC does resampling, it should kill any jitter with it (such as the Apogee Rosetta wich I plan to obtain) . So improving the motor stage and the PSU might appear more straightforward than outfitting the P-700 with an ultra stable oscillator.
There is even another potential oddity here if one uses an external DAC that does resampling: I do know that many of the VRDS series - definitely the VRDS 25 - use resampling internally already - in a rather tricky way to eliminate jitter. Now if this design is being used in the P-700 as well (which I dont know yet) another resampling stage in an external DAC might not be advisable.. (the signal would be resampled twice)
as always .. you solve one issue and a whole lot of new questions appear..

"Overkill" hardly, Ive had two Teac VRDS-T1s side by side one fitted with the XO3 and XOsupply the other standard. both going into a very good dac that had 2x coax inputs switchable.
Both transports same disc switched between the two and the difference is night and day, the modded one has more a relaxed presentation and a sound stage that is much larger and 3d. the non modded one collapses the sound back into the speakers and brightens/thins the sound out.
Cheers George
dougigs
George, slightly OT buy how do you handle the input switching on that DAC?
Ive got one of mine rigged to switch between two SPDIF inputs, using two relays positioned as close to the BNC connectors (and the PCB input) as possible. Still, I worry that this is a messy way to do things. Any advice on switching schemes?
georgehifi
Its the Teac D500 the mate of the P500 that a friend owns, not sure how they do it, but its got 2x toslinks and 2x rca coax so you can switch between 4 x transport if you like from the front pannel select button from memory (maybe relays).
Cheers George
dougigs
Yeah, Ive got a similar switching scheme in a D-700 DAC, which I use in my kitchen setup (it came with the transport). It uses the same switching scheme. Its a row of relays... I actually worry about the lead lengths on it, esp. given their proximity to the power supply. Thats my concern: How do you implement an input-switching scheme thats not going to act as a big antenna?
Some people here have suggested air-wiring the zobel components straight onto the BNC leads to keep things crisp... In a switched setup, do we suggest having redundant sets of passive components wired onto the relay outputs, or just one set close to the input transformer?
dubkarma
A dumb question perhaps, but...
how does one tell a VRDS 25 and a VRDS 25X apart?
Does the X version have "VRDS 25X" printed/silk-screened on the face plate?
The reason I ask is that I have the opportunity to purchase a VRDS 25. The vendor is "almost certain" that its a 25X, but also admits that it says "VRDS 25" (no X) on both front and back plates.
Date of manufacture is December 1995, which strikes me as too early for the X version, which I understood was manufactured only from 1997 or 1998.
If anyone could suggest a fool-proof test for distinguishing a VRDS 25X from a "plain" VRDS 25, Id be most grateful.
I did phone the Teac parts depot in the U.S. and confirmed that the 25 and the 25X have separate service manuals, so I assume that there are at least some electronic differences.
Thanks in advance,
Joel Tatelman.
desjet
Hi,
the 25X model have digital inputs (you can use it as a dac), the 25 not. The schematics are nearly identical.
25X: The Teac logo on the face plate is engraved
25: The Teac Logo is plastic

CROSSY
resampling does not kill but only attenuate the incomming jitter. Like with any attenuator, less in = less out
Lower jitter from the drive is always benneficial, I yet have to find a DAC that is fully insensitive for incomming jitter.

Dear all members,
I read that you all know Teac vrds and Im searching for information.
I have a vrds P500 on a Cayin da2 DAC (6922 valves).
I have an opportunity on a vrds 9 for around 330 ©¤, almost new.
Is it worth upgrading from a P500 to vrds 9 drive ?
Or should I get a vrds 10se or 25x ?
Thank you !

Just wanted to throw in a "satisfied customer" report.
I purchased a "transport upgrade kit" for my VRDS 25 from AES-Audiotuning in Germany (). I asked a lot of questions before buying and got patient answers with many colour photos in reply. Very good customer relations.
The kit consisted of Black Gate caps for the power supply, an XO Clock 3 and XO Clock 3 power supply, and a digital output board with XLR (AES-EBU) and BNC (SPDIF) output connectors (RCA-BNC and XLR-RCA combinations also available).
The parts were well packaged and made it from Germany to Canada in about seven business days for only US$15.00.
I had a local technician install the parts.
Distinct improvement in clarity and detail but at the same time "smoother." Better localization of instruments and voices.
Currently used with a stock Benchmark DAC1. Will soon be trying out a Lavry Black DA10, so Id be grateful for any comments of listmembers who have compared these two DACs.
Regards,
Joel.

Cannot think of anything one may do apart from upgrading the servo power supply with the usual arsenal .i.e better regulators (LT series) or discrete Jung type a la ALW, better caps/bypassed etc.Otherwise you get into the realm of tinkering with the servo icЁfs etc which would be way beyond even some gurus here.

More updates on this?
I also have a dac similar to the benchmark and looking to buy a VRDS transport...
dubkarma
Telstar,
Updates? Well, Im still using the VRDS-25 modified as a transport with parts from AES-Audiotuning; still using it with a Benchmark DAC1; still satisfied with the performance. As a matter of fact, its not far off in performance from my Teac/Esoteric P-70 transport. The crucial difference is that the P-70 has a word-clock input so that it can be slaved to a DAC that has a word-clock output.
In addition, I recently purchased a VRDS-25X. This time I may mod the entire unit and not use an external DAC. Well see.
Regards,
Joel.

My DAC is the TwinDAC+ and I think it is similar to the latest version of the benchmark, but has only one digital rca input and one usb (perfect for me).
Im considering purchasing a sacd transport but Im afraid that with vrds mechanic there is only the expensive esoteric models.
Im considering the DV50s (I know it doesnt have a vrds mechanic) to mod in the clock/fuse parts.
For redbook playback Im going with computer-based playback, so my interest for cd-spinner would be only SACD and DVD-A.
I remember that some Wadia sacd players or transports have teac vrds mechanic but I cannot find which ones.

Which are the essential mods to be done to a VRDS 25 or 10SE for use as a transport?
clock with its psu, then?
georgehifi
Here is a pic of the Tentlabs XO3 and XO supply mounted under the main digital decoder board (board to go on top) is is the best position for it as all leads are kept to a minimum.
I have done close to ten now Vrds-T1 Vrds-10 Vrds10se and Vrds-25s
The difference in sound is very noticable with all models, more extension top and bottom more grunt to the bottom end, yet tighter, top end is more extened and floats out from the speakers, instead of being squeezed out of the tweeter, overhaul a more relaxed presentation yet more dynamic.
Cheers George

Thanks, Ill use for sure XO3 and XO supply, but i was thinking also to upgrade the digital outputs since the main use of the 10SE that Im buying is as transport.
Any more useful mods? I have about 400©¤ budget, covering also labour.
Besides, I wrote to Guido Tent and Ill buy the components from him
georgehifi
When you instal the XO3 make sure you use its better spdif output, it sound better that the Teacs 10SEs.
Thats it youll have a word class transport that will be near impossible to beat.

Yes the XO3 has a spidf output, the 10, 10se and 25 have the same mech and laser the T1 is a little cheaper in its mech and laser but still very good. Yes Sony decoders.

Tentlabs power supply has very good galvanic isolation because he uses chokes in it as well, stick to it.
(galvanic isolation ) the noise of the xtal itself isnt fed back through the power supply into the rest of the system. I think this is what Guido said to me one day.

No but someone once told me they use either a vrds one or a copy of one.
