If I were you I would stay away from the Onkyo, I was looking at the 601 and almost bought it till someone from ecoustics forum show me that the Onkyo stuff are way over-rated, even the higher up version 901 rated at 110w x 7 only capable of putting out about half, and the test report from Sound & Vision tested the clipping occur at 50w!!! save your money and consider Harmon Kardon or Denon.

check out the test reports: http://www.geocities.com/Area51/Hollow/3401/ratevsac.htm
