Upgrading from Wilson Sophia 2's?

Can we get back to Madfloyd's question about upgrading the Sophia 2? I've heard his system, understand his frustrations and would like to read some more opinions in the hope of learning something.

I have Sophia 1's in a 14'W X 23'L with a ceiling that starts at 9.5' on the left side and rises to 10.5' on the right. My system and a 52" LCD screen are between the speakers.
I have tried acoustic egg crate foam, thick gathered material similar to drapes and a thick flat blanket covering the screen. The foam and gathered material tamed the "beast" but the cost was a reduction in imaging and compression of the sound stage.
The flat double thick blanket worked best and with a small pillow on the wall directly behind the system at ear level listening for hours isn't fatiguing albeit's not at 85db!!!
It seems tuning the back wall is a bigger deal in my system/room then the side wall reflections!!!

before doing any speaker upgrades I would probably consult ASC (acoustical science corp) to see if they can suggest some improvement on your acoustics if you haven't done so.
Sophias for the most part I heard them are not really aggressive speakers.
One will be surprise how much acoustics can contribute to the overall sound of a good hi end system like yours.
Good luck-all the best.

I agree regarding having your room checked out professionally. I had pair of Infinity Prelude MTS’s that were supposed to sound very flat across the frequency spectrum. In my room they were aggressive, forward in the treble and fatiguing even on a good recording. Some Core Audio Design diffusers on the back wall solved the problem and gave me a great soundstage with increased depth.
