Hi Everybody. I thought I'd "ask the experts" before I made a purchase I wasn't happy with.

I am wondering how well wireless technology has evolved with regard to using them for rear speakers. I've seen the cheap models Recotron has marketed for a long time, but now there are offerings by both Advent and Sony. Is there interference? Sound degradation? Or will I be happy? Because of wires, I've been without rear speakers for awhile (S.O. objects -- they're not decorative enough) but want to have a complete system back again. Your opinions?

Also, a friend has an Infinity subwoofer he wants to sell me. I haven't seen too much discussion on the unit, except for one post in another string.... Your opinions on the Infinity unit? Thanks!!!!!
