Went to the CES in search of a new DAC to deal with high rez formats. Went to many rooms and heard some good, some great, but mostly mediocre sound. I am interested in the groups comments regarding 2 of the rooms that I found to be outstanding. The Ypsilon room and the Zanden room both were exemplary. One thing that they had in common was non oversampling DACs with tube analog sections. As many high rez DACs as I listened to at length (Weiss medea, BAlabo, DCS, Soulution, Boulder, Playback, EMMLabs, etc) none of them held a candle to these 2 even under suboptimal show conditions. My impression so far with high rez digital is that it sounds slightly better than CD (if you listen hard enough), but is not fundamentally different. These 2 units were different. What gives? Is high rez overhyped? FWIW, I have listened to high end high rez vs CD in excellent conditions and still drew a similar conclusion.
