Why settle for used. You can get a new Audio Mirror D1 DAC for $500 new on Audiogon (sounds like 3 - 4x the price). I just bought one and am thrilled with it. One note, it is non-up/oversampling so if you're not into that philosophy then you'll need to consider others. Doing my research I have seen great products from Scott Nixon, Bel Canto, MBS, Ack,and others in your price range. Look around and do some research and I'm sure you'll find what you're after.
What is the best DAC to buy used in the $500 range
I am looking for suggestions on the best sounding used DAC in the range of $500 used. I have checked the archives but didn't find any useful information. Does anyone have any suggestions on what to look for? Thanks for the interest.
