SOLD. Ayre QB-9 DSD USB DAC in excellent condition. Silver finish. I bought this unit as a demo about three years ago and had it upgraded to DSD status last November. I can confirm this resulted in an appreciable improvement over the 24/192 version. As part of the upgrade Ayre appeared to give the unit a new external casing, so the unit looks like new. Will ship from 14850 in the factory box.
