Вы, Александр, слушаете классику, так? Вот какую комбинацию Вы себе бы выбрали? Андрей ранее сказал, что иметь балансные выходы не всегда значит быть балансным. Что имеется в виду? Я не шибко в этом рабираюсь, просто у ATC только балансные разъемы, длина кабеля, кстати, (предполагаемая), не более 1, 5м.

про классику я к тому, что сушаю, в основном, джаз и вокал, поэтому, требования, думаю, сходные. Потом, у меня вопрос по кабелям. Как Вы считаете, можно ли выбрать недорогие проф. кабели типа , или лучше не экономить?

на 22 да я слушаю все, но классику преимущественно.. балансные бывают и фиктивные(на честную полностью балансную схему деталей надо раза в 2 больше чем на нессиметричную) из современных недорогих честных балансных первое, что на ум пришло Thule Audio иплеер и пред А балансные кабели только такие и брать - изготовленные из нормального профкабеля(например из 4-х жильного микрофонного Канаре) с нормальными разъемами Ньютрик (все затраты 7-10уев на кабель)

вот зацитирую здесь мануал от АТС.... может кому пригодится... есть что прочитать. User Manual: SCM35 Passive
Introduction Welcome. In selecting АТС you have chosen an example of the finest audio engineering available. АТС was founded on a principle of engineering excellence, and that principle still defines our products today. Given the right opportunities, АТС products will deliver exceptional audio performance, but the opportunities will only arise from careful and thoughtful installation and use. Please read the following manual fully. It will help you understand the product and to realise its full potential. We are happy to answer questions and offer advice on any issues that arise through installation or use of АТС products. Contact details can be found at the back of this manual. АТС was founded in London in 1974 by Australian emigre Bill Woodman, who still heads the company today. An enthusiastic pianist and engineer he was naturally drawn to loudspeaker design and after a period working at Goodmans, where many of the names that went on to found British loudspeaker companies began their careers, he struck out on his own.The premise on which АТС began is a simple one, and one that in many respects is still true today: hi-fi loudspeakers tend to be detailed and accurate but of limited dynamic range, while professional monitor speakers tend to express the opposite character. АТС products were designed from the outset to offer the best of both. It's an easy concept to describe, but surprisingly difficult to engineer. The difficulty inherent in designing such loudspeakers is one of scale. Hi-fi levels of accuracy and detail call for lightweight moving parts and delicate engineering. Professional monitor levels of performance however demand far more robust components engineered to survive the rigours of high level use for extended periods.The only way to combine the two is through precision engineering of a class and scale more often associated with aerospace or motorsport. But the results are worth the effort and the cost. АТС loudspeakers, with their unique in-house designed drivers, combine the best of hi-fi and professional to devastating effect АТС has become synonymous with active systems. Choosing to offer active loudspeakers (where the passive crossover network is replaced by active filters and multiple power amplifiers) is simply a result of the uncompromising attitude to loudspeaker design.While passive systems still have their place, and АТС engineering skills can still bring remarkable results from them, "active" is a fundamentally better solution to the problems posed by accurate, high level music reproduction.The АТС instinct is always for the better solution. Not cheaper, not quicker, but better. It was the development of active loudspeakers that first brought АТС into electronics design and engineering. Active speakers demand multiple power amplifiers so АТС from the mid 1980s became not just a loudspeaker manufacturing company but an electronics manufacturer too.The further step from electronics for active speakers to a range of stand-alone amplifier products was natural and now means that АТС engineering is available from the recording desk or CD player output to the ears. From modest beginnings АТС has grown to become one of the very few manufacturers successful across both domestic and professional audio. By selecting АТС you join a group of music lovers, professional audio engineers, studios and musicians across the World that understand and value the engineering that goes into an АТС product - and the sound that comes out.

SCM35 Passive 1. Monitor Placement The subjective performance of any monitor loudspeaker will be fundamentally influenced by the acoustic character of the room in which it is used, and its position within the room. Most often monitors are installed in rooms which are comfortable to sit and talk in. A mixture of carpets, curtains and soft furnishings will help ensure that middle and high frequencies are reasonably well controlled.There may however be low frequency problems; either too much or too little bass. To minimise low frequency problems the monitors should be kept away from corners or walls. Start with them positioned around I metre from the side walls and 2 metres from the back. If the balance is bass-light, the monitors can be moved towards the back walls. All rooms vary and it is a good idea to experiment with both the listening and speaker position until a good compromise is reached. For professional installations the requirements are often very specific. Please consult with an experienced professional acoustician if necessary.
2. Amplification The choice of partnering amplifier for the SCM35 will have significant influence on the performance of the system. Consider the following when selecting the amplifier: • With any passive loudspeaker there is a trade-off between low frequency extension and sensitivity.The SCM35's extended low frequency response means that its sensitivity is relatively low. It is advisable therefore to select an amplifier of relatively high power capabilities. Use of an under specified amplifier will result in the system sounding distorted at high levels and may risk damage. Valve or solid state amplifiers with high output impedance should be auditioned carefully to establish that their characteristic reduced damping at low frequencies is acceptable. • The SCM35 bass and mid driver voice coils are unusually large and operate in an overhung gap. The result is that the SCM35 not only demonstrates extremely low distortion at all levels but also a greatly enhanced effective dynamic range. This exceptional distortion performance, also combined with very wide dispersion, will ruthlessly reveal deficiencies in ancillary equipment. It is advisable therefore to audition the SCM35 with your proposed amplifier and ancillary system.
3. Connection The SCM35 is equipped with a "tri-wire" connection panel that enables separate amplification of the bass/mid driver and tweeter. Remove the linking bars between the two pairs of terminals if you wish to take advantage of the bi-wire facility. The terminals can accomodate either stripped cable ends or 4mm plugs.Always use good quality speaker cable with a 2.5mm2 minimum cross sectional area per conductor (79 strand). Cable of a smaller cross sectional area or fewer strands is unsuitable. For cable runs longer than I Om use a significantly heavier gauge cable. Consult your dealer or consultant for specific cable recommendations. Ensure that the positive and negative terminals on each connection panel are connected back to the corresponding positive and negative terminals on the amplifier. SCM35 Passive
4. Listening The ear and brain tend to interpret distorted sound as loudness and thus underestimate the actual level of undistorted sound. The SCM35, like all АТС monitors, demonstrates very much lower levels of distortion than conventional systems of a similar size and it is therefore advisable to begin listening at an artificially low level and carefully increase the volume. It is also possible for the SCM35 to produce sufficient sound pressure levels for your ears themselves to become a source of distortion and make the sound appear harsh. Any audible distortion indicates that either the system or your ears are being overloaded and that the volume level should be reduced. 5. Care and Maintenance High technology material finishes are used in this product. The surfaces are durable and with a little care can be kept as good as new even under conditions of heavy use. Normally a dry duster will be all that is required to keep the finishes clean. Heavy soiling can be cleaned using a cloth slightly moistened with a non-abrasive household cleaner.
