Ggil, I have heard an even later version of the APL Hi-Fi Denon 3910 with Nuforce 8.02b's(with Cardas adaptors for my single-ended preamp), and I have to say that even though the APL had less than 50 hours of the 200-300 minimum burn-in, that unless you are really way up there in tube-land, that they sound fine(or better). I'm not sure, at this point, that cd's that aren't recorded in analog, to begin with, sound good. This is with little experience in this area, but I will try to update as I go along in my listening.
