Austinbirdman,
I have an older Onkyo 601 and it powers my M60's, VP 150 and 3 QS8's just fine. I have all speakers set to small and my dual SVS subs crossed at 80.
I have used Onkyo over the years and have been very pleased with their performance. Although one shouldn't buy on warranty coverage alone, as with most units if they last 30 days without problems they are usually "in it for the long haul" but the Onkyo's have a 2 year warranty whereas the H/K's only have 1 year.
Best of luck with your choice..
Rick
