Speaker choice? need advice.

As a long time owner of Thiel speakers (Cs2, Cs2.3, and CS2.4), I can't recommend Thiels close to the wall or less than 8 feet from the listening position. Try something else. Good luck!

Scotthobby is right on. Thiel's need at LEAST 1' from the back wall, 3' from corners, 8' apart and 8' from the listener. "Try something else.".

If the back of the speaker must be close to the wall , look at speakers that do NOT have a rear port .

You don't give dimensions for your room but if you can only allow 5 feet between the speakers, headphones might be a better idea. I don't see a way to get a "big, clear wall of music" on a small wall. Much has been written about the AKG 1000 headphones and I know there are other brands that will perform at a level that $1500 speakers cannot approach.

Energy Veritas 2.3i should be perfect. Takes up about the same floor space as a mini monitor on stands, is front ported so you can place it as close to the back wall as you like, is a good match for your amp and is a great rock speaker because of bass performance and oustanding dynamics.

I had a pair in my system for the past year and they are one of my favorite speakers of all time. I recently switched to the Usher CP-6381's and like the Usher line very much as well. However, with your requirements the Veritas are right on the mark, size, sound and price.

Audition a pair if you can.
