Well the 50 watts was a guess, about were the meters are,(which are probably not that acurate) but it is pretty ramdom, and source dependent, not really volume dial dependent, per say. You just can't push the source TOO much.

J Bellemare, that was the exact amp i was considering. If you say it will push the M80's...to LOUD volumes,(like concert volume) with no problems. Plus you really don't hear a difference between it and your old Hafler..works for me.

I will double check all the wires. In fact i will not change them, just check and put the Advents on there. If there is a short, the Advents should shut down the amp also. But i don't think that will be the case.
