Well, I'm jumping on board the Aperion train! Just bought 2 532-LRs, 2 422-LRs, and a 533-VAC. I went with a Hsu sub...don't stone me. :) I have some in ceiling speakers for rears to round out the 7.1 setup. They aren't real high quality, but I'll stick with them for now.
I'm really excited to upgrade my speakers. I am using some 10 year old Infinity's that have served me well, but I know there is a great range of sound that I am missing.
Wish me luck!!
