О вреде и пользе чистящих кассет, или как запороть деку!, А может чистая случайность

Ты думаешь, что всё так просто: купил деку и балдеть пошёл? Интересна реакция жены, если я ей скажу: "извини, дорогая, в этом году вместо моря я себе деку купил." Если уж купил дорогую игрушку себе, то тем-более обязан на море семью везти.
А дека пока не приедет ко мне домой, можно вообще расслабиться: неизвестно ещё, что там приедет да как...

Да слух кривой, нетренированный
Ну вот как такое может быт???:
С тренированным слухом - единицы.    Шучу, но доля правды...
Ты же видел, что мне реально 7ка больше понравилась, на всем материале...

Вот слуховое восприятие - это как раз и есть из области чудес...
А по факту ты сам говорил, что настраивал ОДИНАКОВО, параметры получились ОДИНАКОВЫЕ, в чем разница? Я конечно понимаю что параметры и звучание адекватны не на 100%, но сильной разницы не могет быть...
Слушай, а видео она у тебя не показывает?   Вот там вилка влияет, иногда...

В довершение приведу выдержку отсюда:
Head and Pinch Roller Cleaning
There has been a lot of discussion on NakTalk over the years regarding head cleaning.  First I'll start with the No, No's.  Do not use drug store alcohol with a purity of less than 98%.  Standard rubbing alcohol or isopropanol is typically only 70% pure alcohol with the rest being water.  Denatured alcohol is Ok since it contains 99% ethyl and methyl alcohol with only trace amounts of water.

Just about everyone has their own ideas on what to use.  I'm not sure what Nakamichi officially says, but, when I used to go to the Nakamichi parts department in Torrance, CA they had a display on the counter for American Recorder's Intraclean S-711 head cleaning solution.  They were careful to say that they are not officially endorsing their product, but, they did say that they use it on all the decks that come in for service.  Unfortunately S-711 is no longer available because of a ban on 1,1,1 Trichloroethane.American Recorder now has Intraclean S-721H which is pure Hexane.  S-721H is $10 for a 2 ounce bottle that should last the home user virtually forever.   With some of the older high end Naks they included a small cleaning kit containing a bag of cotton swabs and a small bottle of what I believe is just isopropyl alcohol (probably 90% or better, not sure). While this kit was included with some decks it is not recommended because of the possible high water content.  The important thing is to use something that will evaporate quickly and not sit there.  The worst thing is if water sits on the metal parts.  (S.J.)

Some people like using an old Ampex head cleaning solution from the 50's & 60's.  It is basically carbon tetrachloride.  It works great, but, was banned many years ago because of it's effect on the ozone layer.  American Recorders Intraclean S-711 is no longer available either because it's ingredient 1,1,1 Trichloroethane also deplets the ozone layer and has been known to cause cancer.

Stephan Sank says he uses MEK (Methyl Ethyl Ketone).  It's cheap and an excellent cleaner, but, is known to cause cancer and can royally screw up plastic.  Use in a well ventilated area and don't let it touch anything except the heads and pinch roller. It will melt the plastic parts and can even cause damage to the anodized aluminum front panel.
