DZ,
Please post your results here on running the M60's with the Sony receiver. I posted in another thread that I am able to turn my STR DE995 up to max volume and still not get the response I want out of my Epic 50 HT w/QS8's. In response I'm going to upgrade to the Denon 2805 to see if I have better results. Best of luck.
