What's up with all the watts? A HK AVR230 shows 6*50 with a retail of $549. But a Yamaha HTR-5730 tells me that I can get 6*85 for $299! Is Yamaha overrated? HK underrated? What about Denon & Onkyo? While I'm at it, all the Ascend HT system users, what's the best receiver for a 5.1 CBM + CMT system? The HTR-5730 seems pretty good enough, but is it really? And on top of it all, the sales guy is giving me a HK AVR430 for $660? Sounds good??? Cheers.
