I received an URD on 7/24. No problems reading CD disks (or CDRs). It did not sound too great right out of the box, but now that I have 35 hours of break in, it is starting to sound really good. I suspect that it will get better still by the 100 hour mark. I have so far been using the SPDIF coaxial output exclusively, feeding a Denefrips Pontus II 12th.
My experience with the break in issue does not surprise me; similar things have happened with other components of various manufacture. It will be interesting to see just how good the URD gets when it is fully broken in. If it comes within 90% or better of the Jays Audio unit, I would say it is a bargain. I will post further when I reach 100 hours.
