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 ??

Schiit Bifrost 2 is very good for the money.  have had mine for a month now and like it very much.
I'll be listing my Eastern Electric MiniMax DAC Supreme shortly for $595.00
I believe that it retailed for $1300. new. It has both tube and SS output.
I don't know much about the others that have been suggested here although I can safely say that the EE blew away the DAC in my Sony SCD-C555ES CD player. It has XLR out as well. Check it out.
Used: Schiit Gungnir Multibit Analog 2

New: Schiit Bifrost 2 (as recommended above).

If I was in the market, I’d get the Bifrost 2 and be done with it.
I have been happily using Bryston BDA-1 since 8 years. Currently there are atleat three offers on A’gone which can fit your budget ( under $700) comfortably.
Bryston gears are very reliable and long lasting. I would recommend to consider it.
