QB-9 Twenty USB DAC *New Old Stock* Limited Batch.

Description

The QB-9 Twenty has held its place in Ayre’s history as one of our most popular products ever. The hyper-focused functionality of our USB input only DAC design allowed us to scale up in parts quality everywhere we could; putting this little converter closer to our flagship digital product the QX-5 Twenty than any other product in our lineup.

We have a small batch of “New Old Stock” QB-9 DSD’s that have been upgraded to the Twenty version. These were new in box QB-9 DSD units that never sold, and were returned to swap out the DSD board for the Twenty version to offer through our web shop. They are as close to a brand new QB-9 Twenty as we are going to get; for now!

These units are being offered with our full Five Year factory warranty.

Secure one for yourself today before they are gone; again!

Domestic Orders will ship in 2-3 business days.
