I've got an MSB S-200 power amp and an Analog DAC. That power amp is awesome no matter what the source. I thought I had great digital sound with the Analog DAC/S-200 - had it that way for many a year - but just upgraded my vinyl system and got a Herron Audio line-stage preamp. I ran my signal from the Analog DAC to the Herron Audio CD RCA inputs, and from there to the power amp, and everything that plays through that system sounds SOOO much better now than it ever did before.... The Analog DAC and S-200/S-202 may have been designed to work synergistically with each other, but there are better ways to get great sound from those components.
