Second owner. Excellent condition with no blemishes that I can see. This is an original 24/192 version, which can be upgraded to DSD for $500. This particular unit is already in queue to be upgraded. Original box included. USB cable not included.
The QB-9 is one of the best USB DACs on the market. Unlike most USB DACs, the QB-9's USB implementation is great by default and doesn't require tweaking. Check out all the great reviews.
Note that a used DSD version typically sells in the $2300-$2500 range, so it's quite a bargain.
I'll pay shipping CONUS. Please add PayPal fee (or use check/money order).
