How Important Is a Receiver’s Power Output in 7-Channel Mode?

Q I love Sound & Vision’s reviews for the objective bench tests, though the results often don’t seem to sync up with the reviewer’s opinions. I’m looking to replace my damaged but terrific sounding Pioneer A/V receiver with a Yamaha RX-V773. The RX-V773 and its siblings get stellar reviews, but they exhibit a huge power drop-off
when driving five or seven channels compared with their two-channel measurements. Pioneer’s VSX-52 receiver delivers around three times the power as the Yamahas into seven channels, though this doesn’t seem to make a difference in the subjective part of the review. Here’s my question: Is a receiver’s power output in seven-channel mode not an important factor when it comes to sound quality? Just looking at test results, I would have expected the Yamahas to get a poor rating for sound, but their reviews are consistently excellent on that point. &mash;Jonty Rees / Austin, TX
