I use a Proceed PAV/PDSD pre/pro with Proceed Amp-2 and Amp-3. The PDSD provides 5.1 processing with balanced outputs for 5 amps plus a sub, and analog pass-through for the PAV. My amps are closer to the speakers than the processor, so balanced lines are important. I use an HDMI video switcher to select between an HD-DVR and a PS3-80. A Velodyne SMS-1 provides room correction below 80 Hz for a Velodyne HGS-15. Speakers are a pair of KEF 104/2 mains, 200C, and 102/2 surrounds, all biwired. I think you can find a PAV/PDSD pair on Audiogon for about $1K. MSRP was about $10K, but that was some years ago.
