Digital amp beat them all? Audio Physic Strada .

Marakanetz, I believe that the TacT in it's basic form is pure digital in and out, the only conversion being that of PCM to PWM. Digital crossovers are standard. AD input and DA output are options. By the way the designer states that the room correction offers the most improvement.

Hmmm... What I believe is that what TACT unit accommodates in one box isn't necessary to the vast consumer and that makes this unit overpriced (please forgive me in re-directing this discussion). There are some consumers that don't want built-in DAC or correction. I admit that this unit accommodates the state of the art DAC that is able to bring regular red-book CD playback to the level that is very close to vinyl even with poor transport. In fact if this unit had an option to break up into different boxes it would be much more marketable. TACT RCS is relatively new thing in the audio market and somehow already there are used units with drop bellow the half of its price. I'll expect this unit to be cheaper but than again TACT will come up with something new and will descontinue the previous as all the manufacturers usually do. In my situation I would just only ask the manufacturer to brew for me a custom unloaded version without correction and even DAC leaving only digitally controlled analogue volume control and get their DSP later until my CD collection will be someway even close to half of my analogue. My CD collection stays for not long and serves for information purpouses only(meaning i sell them right after I've listened to them and buy different ones) so the demand on reproduction quality is quite low in comparison to analogue. And finally It is not even neccessary to have separate boxes It is good enough have a basic preamp box that can be upgradable by insearting cards just like you do it on your home PC: card for DAC, correction digital Xover, phono, ADC etc...

I think, I'm finally beginning to understand you.I do believe that the Tact approach is revolutionary and as such be forgiven for not making typical components. Their attempt to tackle what many belive to be the final frontier, room correction has opened other possabilities as demonstrated by thier system approach. With digital crossovers that allow for proper time and phase, minimal driver overlap, minial lobing, super light drivers and flexibility of placement not only as a convience but for better perfomance. Thier amplifiers are part of this concept and allows for super fast control with little smearing. Maybe, I'm missing something but it all makes a lot of sense to me, and what I've heard suggests thier on the right track. Considering the R&D costs and the results I think we are looking at something that is closer to a bargain than not. Perhaps we need to let go of our previous concepts and allow for a different appraoch.

P.S. as this thread was started re: digital amps, I should point out that in theory the TacT should be able to play with the same resolution regardless of volume and never clip (Tube lovers rejoice, forget pleasent (even order) vs. unpleasant (odd order)how about none?).

Like the perfect sound forever with no distortion that was promised by the Compact Disc?
