If this setup is for HT only, I'd buy the Outlaw receiver and the separate 5 channel amp. My brother's friend has this setup. He liked the external amp because it is very muscular. It reminds me of the Hafler or Ati 5 channel amps. You could probably get both items on the used market very reasonably priced. That's what I would buy, for inexpensive, powerful. (I don't think SQ matters as much in HT as it does for music, YMMV)
power, SQ, inexpensive... pick any two.
