I have an all-Aperion setup, but use the 632 bookshelves + sub rather than the towers. I have the same center that you're looking at. I diasgree about the previous assessment with them being thin and harsh. Perhaps my larger speakers make up the difference, but I also tested the 532s I use for surrounds as front speakers. I thought at the time they seemed underpowered, but that may have been because they were fresh out of the box and I did absolutely no setup/calibration - just plugged them in to my new HTR-5990 and turned them on when I had everything sitting on my living room floor. I initially had the same reservation with the center channel (thought it was muddy). I normally like the dialogue boosted up nicely because years of drumming have taken a slight toll. My concerns with both the 532s and the center went away when I I got my HT put together and properly adjusted. I even like the in-ceilings I'm using. Aside from sound, you can't beat the build quality, customer service, return policy, etc. I think they are definitely above the curve on the bang-for-the-buck scale.
Cheers,
Kevin
