Regarding the McIntosh DAC2. Mine malfunctioned and I really didn’t go back once I got it repaired. I moved to the Aurender and Holo May DAC KTE during the long down time of my DAC2 and the combination Aurender/May DAC were a major upgrade, but here is a pretty good evaluation of my integrated the MA12000 (with DAC2) against much more expensive equipment. They also compare the DAC2 to the new PS Audio DAC. Worth a look.
