More than likely the denon, they are a bit lean and plastic sounding sometimes as transports.. I can tell you I have been bouncing around transports, many variations of the basic concept of a disc reader can render far different results, as of a week ago I refound the fact a dac you get so use to soundwise can always give a different flavor when you change the transport, and also found some effect with digital cables.
Also the power cords in my case have had some more dramatic effects, I tried a transport once with a 12 gauge silver coated copper PC and found it hard and thin, then I decided to go try a 10 gauge copper with shield power cord and it added much weight and midrange warmth to the same Transport with perfectly balanced sound. The dac is effected too by power cords, but in my experience to a smaller degree than the transport itself.
I know it seems silly and well it is just a laser with a clock and digital out circuit, but it is effected by power supplied to it. And if in some way your power happened to fluxuate in the wall and one day it sounds pretty good and another it is something wrong and you changed nothing, it is probably from voltage drops in the house, it happens to me and I can pretty much now pinpoint the times it just sounds better during the day..
Damn I need dedicated lines one day. But I had weird things happen when they do some power work in the neighborhood and then all of a sudden my sensitive gear changes tone.. But this has not happend since they installed a new transformer on my street about a year ago.
