Spend some $$$ to get a better receiver.
A few years ago I went from an Onkyo 806 to a Pioneer Elite SC27 - what a difference!
The spaciousness of the sound & balance destroyed the Onkyo.
I do have an Onkyo 605 in the bedroom that is still running like a horse. I would buy another Onkyo for my 10 year old sons room, but never for the living room.
