Ayre Acoustics writes: “QB-9 Twenty’s Upgrade circuits, fresh off the line! There are still a lot of first and second generation qb9 USB DAC’s that could use an upgrade! From all the emails and phone calls we have received this year by those who upgraded, it’s apparent this DAC is just as relevant as ever.”
“If you need a simple, dedicated USB source solution, the QB-9Twenty is worth its weight in sonic gold.
Pairing it with an amazing @aurender_official, @innuos, @lumin__music, @sgreencomputer or other USB capable streamer or server will guarantee an amazing sound and user experience too.”
