OK...I just hooked up my new Denon 6.1 1705 receiver and...it doesn't play nearly as loud as my crappy Sony 5.1 htib receiver! What gives? Some specs: My old sony receiver was 100w/ch, and the Denon is 75w/ch. I was told by the guy at Tweeter that, give or take a few watts, the sound output wouldn't be much greater or weaker. SO, I decided to get the Denon b/c of the better build quality and wealth of features. BUT, now when I crank the Denon to a pleasing volume (about -18), I definitely get some distortion/hiss from my center speaker and I know that can fry speakers. No matter how much I cranked my sony, it never gave any kind of distortion. It seems that the Denon's sound is really tinny, especially in the center speaker. The volume is also all over the place--whisper quiet for dialogue, then booming loud for effects. And yes, my speakers are calibrated with Avia. **So what's the deal? Is there some setting on the Denon that can make it play louder and with less distortion? Or should I send it back and get a more powerful receiver, like one with at least 100w/ch? I see a 6.1 Yamaha receiver with 125w/ch that I can get at a good price, would that be more powerful and play at a louder volume? Here are some further specs about my setup: JBL E80 for front L/R (91db sensitivy rating), EC35 center (91db sensitivity), SVS PB10 subwoofer. My room is 9X19X13.
