From reading tons of material and looking over the specs, If I were you, I would compare the M60 set up you want to this B&W set up: B&W CM4, LCR600S3, and DM600S3. This will be more of an equal match. I have listened to the B&W 603S3, and I wasn't impressed. When I listened to the B&W CM4, I was blown away. For my ears, they sounded better than the 700 series. I haven't heard the M60 yet, so I can't truly comment. Another speaker setup I would consider is the Oxim Rocket HT pacakage #1: RS 750 Sig Front, RSC 200 Center, RS 250 Rear. I have heard that these speakers are equal to the B&W 700/800 line and Paradigm Reference line. The rockets are said to be a little more relaxed than some speakers. Let this forum know what you finally choose!!
