I have a Pass Labs X150.5 (class A/B) 300W x 2 into 4 ohms and love the darn amp. I have yet to push it into distortion and yeah it may put off some heat but as long as you give it some breathing room or if in cramped spaces a couple of 12 volt DC cooling fans will do the job.

My Dali Helicon 800s came alive when I connected the Pass X150.5. I use the the amp on the main L/R channels and an Onkyo TX-SR875 on the center and surround channels. Works fine when watching movies and now I'm blessed when I want to listen to music. (Also have a 2 channel tube pre)

As always class A/B amps can cost some $$$ but AGON can help with that if you don't mind. Since you are picking up a Rotel pre/processor cost shouldn't bother you too much. Should be able to find a great amp(s) for +/- 3K.

You will be glad you went class A/B!!!


Edit: New amps will cost some $$$ per watt.

Cost does not bother me "too" much. But sometimes the wife is a tad surprised to say the least ! You also have a 2 channel tube pre ??? Lucky you! That must be a very sweet set up !!!
