hey all, been reading the board for a while trying to make up my mind and yesterday the m50's finally came in. Very happy with them so far but have a couple questions.

I have them powered by an HK430 and was wondering how much i should be cranking up the receiver. I haven't heard any distortion so far but the -85db - +db scale for receiver volume has me a little confused (first decent receiver/speaker combo for me). I don't want to damage anything but want to make sure i'm getting everything out of my speakers. I set them to large in the HK menu and have it in stereo mode with no sub.

Also is there any point where the speakers are too far from a back wall? Or does it just matter that they aren't too close. Right now i have them about a foot away from the wall.

Thanks guys.

Adrian
