Audio Research 100.2 vs. 150.2

Hi folks. I'm looking for comments and insight from those who have experience with each of these amps. I'm using the 100.2 to drive Harbeth Compact 7's and am enjoying the sound immensely. However, the 100.2 runs somewhat warm for my new in cabinet installation. I auditioned the 150.2 with my same preamp, CD player and speakers at a local dealer and found the sound quality inferior to my setup at home. Obviously, room acoustics may have played a roll here. Basically, I'd consider switching to the cool running 150.2 if there is no loss of the beauty found in the 100.2--which many have said is a real ARC sleeper. Any help on this is appreciated!

I have heard the 150.2 many times at my dealer back when I was looking for a new amp. It came down to the ARC 150.2 or a Pass X150. I was able to hear both driving Maggie 1.6's. I ended up with the Pass since I felt it had a more natural presentation overall. In my opinion, the ARC 150.2 is still a good amp, just a bit analytical and forward in the upper mids and treble.

Regarding your 100.2 and its new home...maybe add one of those small exhaust fans on the backside? A friend has done that and they are almost whisper quiet and extract a fair amount of heat.
