The sensitivity of the Monitor 11's is 94dB, the CC-370 is 90dB, and the ADP-370's is 85dB. All measurements are 2.83V/1m. The Ohm ratings are 8 Ohms nominal, but the Monitor 11's go down to 3.4, the CC-370 to 6.4, and the ADP-370 to 5.1. You can see more of the specs here
on Page 4.
My Onkyo does 130wpc x 7. This is only a two channels driven rating. It is a THX Ultra2 receiver.
I currently listen to to my system at reference level and wish to continue to listen to it at this level.
My room is only about 16 x 15 x 7.
I think I need an amp because I blew two tweeters about six years ago and I blew at least one tweeter several weeks ago.
You're right on about the Onkyo causing your tweeters to blow. This is a classic example of "too little amp". It's the distortion/clipping that actually fries the tweeters...
Your L/C go down to less than 4ohms, AND your 4 surround speakers are inefficient....
If it were my money, I'd go ATI.
On paper, the ATI amp is rated slightly lower than the Emotiva. But, ATI is very conservative about its ratings. Although they both rate their amps all channels driven, 20hz-20khz, the ATI has less THD in doing so. ATI also gets points for their 7 year warranty, clean appearance, and stellar reputation.
I have no practical experience with Emotiva amps. I do have practical experience with Sonance Sonamps, which, are made by ATI. And they sound incredible. *very* transparent.
