Asking $1100, plus 3% PayPal fee and shipping (within CONUS only) for my Ayre QB-9 DSD in silver (includes Ayre box (not the original), manual and power cord). This was a long-time Stereophile Class A+ recommended DAC (“high-resolution digital files popped with life and were marked by a natural flow and physical impact . . . . Ayre's QB-9 is well engineered, offering excellent performance in both the analog and digital domains”). There are many other positive reviews on the web.This DAC works flawlessly. The unit is in excellent condition, although I have conservatively rated it 8/10, due to a couple of tiny black marks on the side (none on the front face), which I have shown on one of the attached photos. I am the second owner, having bought this used from an authorized Ayre dealer. I can honestly say that this DAC was the biggest bang for the buck audio purchase I have ever made – its sound is clear, detailed, musical and organic. I’m selling it only because I have moved up to Ayre’s current top of the line DAC (unfortunately, at a much higher price). From the Ayre website:
