I’m looking at purchasing a Yamaha HTR5560 receiver. My only reservation is a thread that I read a while ago on this forum. Someone had the RX-V630 (which I think is the same receiver) tested at an independent lab and discovered that it was only capable of generating 27W with all channels driven!? My concern is that I’m looking to drive speakers that are fairly inefficient (88 dB sensitivity) in a room that’s about 2000 cu. ft. Does anyone have a similar arrangement that could chime in? One important thing to note is that I’m only using it for 5.1. I know that sounds weird, but I have a BB gift certificate that I need to use up and currently the 5560 is on clearance and costs less than the 5550. Would the 5550 be a better choice (I don’t need the preamp outputs of the 5560) or does it suffer from the same affliction. Btw – has anyone verified the results above? Just curious.
