Preliminary listening impressions - no background hum or buzz, very quiet. Amps sound extremely nice! Nice clarity and soundstage, bass is quick and tight.... my goodness. I would say after about 6 to 8 hrs of play time, the sound really came into its own. The bass improved significantly, sound stage is staggering, highs are sweet and the mids are right where I want them. Listening to this amp play was pure pleasure. I am really looking forward to more "seat time". You really are able to pick out subtleties on a CD that you have not heard before - even with my modest system.
