Well, not in terms of running temperature, but I have always found the NAD, Arcam, and Parasound warmth appealing. I am currently running a Mythos ST system and will be adding a Paradigm system upstairs in the near future. Both rooms are approximately 20x20x10.
I have looked at the Bel Canto offerings and loved their sound in stereo setups, but haven't heard a Bel Canto HT setup or Nuforce setup, but both sound appealing. My concern is that they may be overly bright with the Def Tech setup. There is a Anthem/Arcam dealer nearby so I hope to hear some combinations of the D2 with some of the amps they carry, but would appreciate any feedback or recommendations in the meantime.
