Upgrade time - Trade Pre-Amp/Mono Blocks for ALL IN ONE Receiver

I have been fed up with all the wires behind my current system. It's a huge pain in the butt to do anything in the tight space I have for my main home theater gear. Right now I have a B&K Reference 50 paired with 5 Marantz MA700 mono block amps. The amount of wires routed for the mono blocks takes most of the space up. The pre amp does not have hdmi. I have to run wires from my hdmi sources to the TV. The whole thing is a rats nest and I want a system without all the wires. I am looking for a quality receiver that can run 2 Paradigm Studio 100's, and 3 Paradigm LCR 450a's. I love the mono blocks, but I could really clean up the area and save a ton of energy removing them. I could remove my mono blocks, vhs, laser disc, cd player, and dvd. With a HTPC all I would need is my receiver. The HTPC will handle everything. This would only use 2 wires saving tons of space. Of course I would still have the mess of speaker wires. Can someone recommend a good receiver with a capable amp built in?

I know this would be a mess but what if I kept the mono blocks and purchased a up to date receiver to run as a pre amp? It would help me eliminate all the other cables by having only the 2 hdmi vs all the video and audio cables I have hooked up. The mono blocks would still have tons of wires.
