Hi JLP, just to clarify, you can put 200 clean watts into the BP 8060's with no worries. Remember that the wattage rating of an amp describes the point at which it begins to run out of the ability to stay clean, or to stay below a certain level of distortion in tech terms. It does not mean that the amp is putting out 200 watts on a continuous basis.Originally Posted by jsampsell 
I say "hiss" but it isn't what that implies. A very quiet, barely audible "buzz" may be a better description for it. With all of my electronic equipment off in the room except for the XPA-5 and the AVR-4311CI, I can barely hear the "noise" I'm describing. But that's after I upgraded my interconnects to 0.5 meter Vampire Wire. Originally I just used some better-than-cheapo stereo RCA cables I had lying around. They were all the same brand and same length so I figured they would work. Not so much. The buzz was very loud and annoying. I did some research here on AVS and the most common answer was that Emotiva amps aren't the quietest amps. I just assumed that meant that it was fairly common and that if it wasn't noticeable from the listening position under the most quiet situations you listen to something in that it was fine. Of course, the Vampire Wire interconnects made a night and day difference for me. I am very glad that is the case. I was contemplating sending the XPA-5 back.

If you're listening to some nice background music while you send a few e mails, that 200 watt amp is likely putting out about one watt on a continuous basis! Speakers often become damaged by someone playing a low-powered amp at a high level, which will of course cause that amp to distort, as it exceeds its rated power, and begins to send clipped output to the speakers...which jack-hammers them. I hope this helps - best, Joe
. Yes, it's normal with the amps in that series to hum for a little while when they are first connected, and yes, it goes away after a bit, just like you experienced. Our older-style amp designs have a warm-up period, while our newer designs don't. I am glad to hear that they sound great!
