Onkyo TX-SR603X vs. Yamaha RX-V657
I'm looking @ moving to a new receiver and I think I'm narrowed down to the Onkyo TX-SR603X vs. Yamaha RX-V657. I currently have an RX-V670 which I've enjoyed, but I also really like my in-laws' TX-SR701. I'm having trouble finding editorial reviews on the Onkyo, but user reviews seem very positive. The Yammy gets good to raving reviews, but I wonder if I have efficient enough speaker to get the best out of it, based on some of what I've read. Speakers include Cambridge Soundworks Model 6 fronts, Yamaha NSAC3 center, and NSA770 rears (no sub yet, but I'll be looking as soon as I have a handle on this receiver thing). I'd really appreciate any input. I live in a rural area and there's no place around here to listen to them side by side (or at all for the Onkyo, except in the middle of a crowded Circuit City :( ). btw, can anyone shed some light on what Onkyo means when they say the TX-SR603X has "Enhanced IPOD Compatability"? I know they make an iPod dock, but that's supposed to work with any Onkyo from the last 10 years.
