I was wondering what would be a good sound combination A/V receiver for the M3's. I'm interested primarily in 2 channel sound with CD's and the odd time playing a Blu-ray concert vid from a PS3. I know to take full advantage of Blu-ray hi-def capabilities you need at least 5.1 channel, but I may just stick with the two bookshelves and add maybe a sub.

About fifteen years ago I had a Yamaha receiver with the Paradigm Titan bookshelves and a sub and the sound was remarkable. I tried the M3's recently with a Sony STRDG720, but was unimpressed so I sent it back. I blamed it on the receiver. My budget is about $300-$500, and I lean towards Yamaha. Any ideas?
