I have the EP500 but I also built my in-laws system which is all Paradigm with an SVS PC Ultra sub. I do like the PC Ultra, but find I like the sound of my EP500 better. However that's not a fair comparison as they are in drastically different theater rooms. One day It'd be fun to steal the PC Ultra for a weekend and do a head to head with the EP500 in my space. Unfortunately due to the SVS being in a basement and gravity not working in my favour, and general laziness this probably won''t happen. blush
I do want to upgrade to the EP800 however, but need to let the M5HP-OW upgrade settle in 1st!
