jake, thanks for your thoughts.
my reason initially for not listing the M80's as an option was the fact that they are 4 ohm.

My new Onkyo 705 will probably not be able to run them but it would run anything else in the product line. I suppose it isn't a major conscern since i can connect the other speakers to the reciever and then the M80's to a 2nd hand stereo amp.
