Best used DAC under $750.


I am currently using the DAC section of my Mac 2500. Would like to have a separate. Also would like xlr outs. Not looking to buy new or spend more than $500-$750. I appreciate your recommendations from your experience. I have owned several separates in the past. Antelope Gold, Wadia 121, AMR 777, April Music ??

Without a doubt the giant killer DAC for even less than what you stated is your price range is the ifi Micro DAC2. I cannot believe what I am hearing with this! Buy it and save the extra money for a good cable. I cannot believe others out there charge what they charge for their DACs when this one kicks some serious rear....
Good luck!

Just curious what you compared the iFi to
Mytek Liberty and the built in DAC in my Marantz UD7007.  I find the ifi to be as good as the Mytek for a 1/3 of the price...
A used Musical Paradise mp-d2 mk1 just sold on USAM for $500.
A mk1 or mk2 would offer a lot of flexibility to swap tubes and even caps.
Audiocircle's disc less forum has a lot of great experimental info on this DAC.
A good, used Ayre Codex might be your answer. It is near that price range used, or slightly above. Also has XLR outputs.
