What I have done is gone for an older model Pioneer SC-1227k as it has the pre-out's and bought a better quality used 5x200w channel power amp.
Now I am getting the LFR's so I will drive just the front 3 channels with my power amp, and leave the rears for the receiver. I gave up the THX, but I might swap my 3 year old THX 1126k unit for downstairs as it has the 12v trigger that would be nice for the amp.
