smokey, if you haven't already pulled the trigger on something else, I would suggest you get just one of those 2 channel onkyo budget amps and use it to power your M60s. I did that (with the same onkyo amp) primarily in order to relieve some of the burden from my Denon 2802 during action movies. With a separate amp for the fronts your receiver only has to power the center and surrounds - a much easier task since they're probably rolled off at 80hz, right?

It may not have been absolutely necessary, but I sure feel better cranking it up loud (don't have to crank as high to achieve the same spl levels either). There seems to be some improvement in action movies when the sh1t is really hittin' the fan - but that could be my imagination.
