Lots of great recommendations here. I'm sure they all sound fantastic, so at this level it really comes down to your personal preferences. What properties of a DAC are most important to you and what aspects would you like to improve upon if possible? I'll just mention the Metrum Pavane as another potential option to explore. Best of luck.
Best DAC for over 2000
I recently purchased a PS Audio DSD Directstream DAC. I had the Perfectwave DAC and found it to be very good but the DSD DAC was just phenomenal by comparison. With the upgrade deal I paid 4000 for the DSD DAC (6K new) but now I am wondering if I should also pay to keep and upgrade my Perfectwave for another 3K or just look for another DAC. I have 2 different music rooms and could use 2 DACs. Is there anything out there that compares?
