Mandrake, far too much concern is expressed about 4ohm rated speakers in general and the M80s in particular. Many receivers, certainly including the Onkyo 806, will work very well with them. If you do want to get the 806, note that the best buy at the moment appears to be the factory refurb available for about $600($U.S.) from Accessories4less . They are an authorized dealer and now ship Onkyo to Canada, although that wasn't the case previously.

Enjoy the music, not the equipment.
