Ayre QB-9 DSD USB/DSD-Capable DAC Near Mint

Like-new Ayre QB-9 DSD for sale. When I say, "like new", I mean the physical and functional condition. This QB-9 DSD is actually about three years old and and has more than enough hours on it to be broken in without being overused. I'm the original owner and got this directly from Ayre after writing a review about in "Positive Feedback." It was my reference DAC for quite some time, over a Berkeley Alpha Series 2 with a USB-to-S/PDIF converter, until I purchased the Ayre DX-5 DSD and, later, the QX-5 Twenty, both of which have better USB DACs. The QB-9 DSD still sounds wonderful though in its elegant simplicity. This is NOT an upgrade. It's a full blown QB-9 DSD from the last generation and includes enhancements that improve the sound any digital source sent by USB, not just the ability to do single DSD on top of everything else (although it does that well). A fully-balanced, zero-feedback design, the Ayre sounds as sweet as can be but does have RCA connectors for single-ended system, which is how I have mine connected now in my backup system (just for fun). Please feel free to ask me any questions but no lowball offers, please. Thanks very much.
