Upgraded to Twenty status in November 2019. In original box with stock Ayre power cord. SR fuses added two months ago. Increased the performance even more....  Only selling due to moving up to the QX-5 Twenty. This is the best DAC I’ve ever had in my system. Read the reviews and the forum about the upgrade here on AS and you’ll know. For those who don’t, the Twenty upgrade was more like a rebuild. Almost everything inside the case is new. USB only but if you’re using that interface you can’t beat it for anywhere near this price. Thanks for looking and please send any questions. UPS shipping in the continental US is on me at the asking price.
