YMMV but I have found my Quads to be extremely sensitive to room placement, room treatment, and quality of gear upstream, more so than any other speaker I've ever experienced. Once everything is "just exactly perfect" however, they are the most incredibly "real" sounding speakers I've ever heard as well.
Before doing anything else I would have them refurbished to their original state by a pro. You could go through 50amps and none will ever sound right if the panels aren't 100%.
Once you know your panels are good, I'd invest in a box of OC 703 insulation (about $120 for a bunch of panels) and $35 worth of acoustically transparent fabric and build some quick and dirty room treatments. Build some corner bass traps too - they were a HUGE improvement in my small basement listening room. Put some panels directly behind each speaker, and some behind your listening position. Don't worry about the side wall reflections as that will have the least sonic impact on the Quads.
Finally, experiment with speaker placement in the room, pulling them out angling etc. In my near field listing position I've gotten the best results by pulling them about 1/3 of the way into the room, putting a small object behind each back leg to tilt them forward (careful they don't fall face down), then toeing them in so that all of the corners of the panel are equidistant to my ear.
I've only tried an MC225 and a Marantz 8b so far on mine. The 225 was nice but the 8b was better, seemed like the Quads bass really tightened up with the 8b.
