I just purchased a pair of M22's based on great user advice gleaned from these pages. (You guys really should get a commission!) While I anxiously await the arrival of my speakers I am looking to purchase a receiver.

My local stereo equipment store sells Yamaha equipment ... r-s300(50Wx2) r-s500(75Wx2) and r-s700(100Wx2).
If anyone owns or has experience with one of these I welcome comments on quality and, more specifically, advice on which unit would be suitably powered to run the M22's. I have no interest in an HT setup. I would like to purchase a decent subwoofer in the (hopefully) not to distant future.

This is my first foray into better quality audio equipment - my listening experience is limited to mini- systems, walkman/ ipod-type players, and the tinny-sounding speakers in my civic. My taste in music is all over the map, but mostly blues, jazz, folk, rock, and classical.

Thanks in advance for your comments!
