LOL, I did sound a little curt, eh? Not much time for this stuff anymore unfortunately.
I was looking at a 3 channel amp from ATI before I settled on the two channel Onk from 2x6. It seems like the amps in your receiver should be able to power SOMETHING, don't you think? I'm very pleased with the addition. Seems to have improved the HT's dynamic ability (could also be placebo effect) and has definitely given me a little peace of mind. Not cranking the volume knob anywhere near as high as I was.
