Hi Badger

I think you're gonna love those M60s. The Sony may not be up to the job of adequately driving them. Check ratesvac for comparisons between real world output and rated outputs of various receivers. http://www.geocities.com/Area51/Hollow/3401/ratevsac.htm

I have a Sony STRDB1070, rated at 100 watts x 6 channels. I thought it sounded pretty weak. Ratesvac tested this receiver as really putting out only 31 watts per channel. I think the STR DE-825 puts out less power than the 1070.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
