i suppose it is hard to isolate performance to just the DAC; but i do think that my perception of the performance advances of the Playback Designs is likely due a great deal to it's unique DAC design.
the DAC in the Playback Designs MPS-5 has an open architecture; it can be 1 bit-5.6mhz or 32 bit-196mhz, 72 bit-496 mhz or anything they want it to be. thru the USB port the software can be updated to whatever they want. algorithms can be updated.
this approach; properly implimented.....would likely trump any older set of 'off-the-shelf' dac chips. and would also be likely to stay at the top level of performance longer since it can be upgraded thru software.
the challenge, of course, is 'properly implimented'.
