Audio Aero Prima MKII v/s Unison Research Unico

I love my MK2 and have had an AA dealer and a fellow Audiogoner say that it beats the MK3 thanks to livelier dynamics and better bass impact. I auditioned the mk3 but not in A/B with mine. I haven't heard the Unico but I have had a lot of CD players come through my system and the AA is a winner. See my system page for lots more info.

Your speaking regarding the Prima amp vs. the Unico amp...correct?

I owned both the Audio Aero Prima MKI amp and the Unison Unico. The Audio Aero is dynamic, detailed with a good soundstage. I assume the MK II would be even better.

The Unico on the other hand was the worst sounding amp I heard to date - veiled, lifeless and boring. Of course, I did try tube rolling and if you like it even more boring and lifeless I guess you try some different tubes.

Not much of a questions in my opinion. The same is also true for their CD players. The Prima CDP is much better than the Unico, although the Unico CDP was not quite as boring as the amp.
