I have a Decco and borrowed a friend's Nova. Tried 'em both in my office system as a preamp/DAC and using a tube amp. I couldn't tell the difference between the two with Redbook CD material I had burned to my laptop in AL format. My impression was that the amp section of the Nova was a very little bit better than the Decco, but it's a small difference if any. I kept the Decco and happily use it in my office system to this day.
