"Wow. How does the Playback Designs accomplish what apparently other players cannot? What is the difference or new innovation in a technical sense? The designer must be doing something special or unique?"
the Playback Designs MPS-5 does all the obvious things right; a transformer instead of switching power supply, excellent analog output stage, a high quality Esoteric transport, and digital inputs for use as a server DAC. beyond that Andreas has somehow eliminated jitter both from the Esoteric transport and any digital input....and he has a totally custom designed, programable DAC.
it's the combination of all these elements which results in the performance. the hard part for the competition will be to compete with Andreas's digital design since it's proprietary; also meeting the price point with all the value.
