Hey guys,
After much thought, I've decided to keep my current set up. Here's what I have

1) CS400 center channel
2) RT55 Bookshelf speakers
1) PSW250 8" sub

my question is, what rear(s) would you guys recommend to go with this current set up.... Yes I know my equipment is on the "old" side, but I've NEVER pushed it and the sound quality to me is awesome!

***in the process of upgrading to an LCD possibly 40"-42" t.v. and Receiver. I currently have an ONKYO TX-DS747.
