@ Mbovaird, Hi, I was waiting patiently for you of all the posters here!, I knew you would come back and say what you did of the Boulder amps, my post earlier on this thread ring TRUE!, they suck!, I also knew you would love the Dan D Agistino amps!, He is the same designer of my Krell 700cx stereo amp!, my next amp will be a Agistino amp!, running hot does not bother me, My krell 700cx gets hot big time!, In the winter, if we drive it, and play it for a few hours, it will warm our three bedroom 2 bath house, saves on the power bill when we do that, we get to enjoy tunes, and do not need the central heat on, LOL!, your description of the Dan D Agistino amps is spot on spectacular!, Happy listening!
