NAD baby, the smoothest, cleanest, most dynamic power. Had the mid fi jap offerings and was not impressed with overall musical ability. Though Denon puts out a good product they do not make audiophile grade stuff, more H/T oriented than music. I for one don't think they are in the same league musicaly as Rotel, Arcam, NAD, B&K, McIntosh and others.
You will never find any of that mid Fi japanese stuff in a high end system, shall we say driving a pair of Focal Utopias or Dynaudio's.
