You've read Amir's review of this DAC, measures in the top 4 of all that he's tested to date, so I won't wax poetic. It's in excellent, barely used condition, with factory packaging and everything as originally sold, including mic, manual, set up guides, etc. I bought this to stick my toe into MQA, and my 65 year old ears couldn't tell the difference, so I'm selling this and saving $ by changing from Tidal Masters to HiFi. $675 FREE CONUS shipping, sorry no shipping outside lower 48. I'll answer any questions that I can. Thanks for looking.
