Up for sale is my 3 week old Matrix X-Sabre DAC. I purchased this and a Concero at roughly the same time. I think the X-Sabre sounds better, but for my work setup, I am sticking with the Concero. This is an amazing DAC and you can read the review thread here.
$OLD shipped (to CONUS, International will pay extra) and I will eat the Paypal fees.
