Very small room systems and synergy


I have been trying for 20 years to put together a system for a very small (10' x 12") listening room and still haven't gotten it right.  I am currently using KEF LS50's with a NuPrime IDA8 integrated with moderate success.  I realize I really don't like metal dome tweeters and I've been drawn to class D amps.  This is probably due to my budget constraints of $2000 - $2500.  Does anyone have any input for me on this?

I also have a small (11' x 12') listening room with LS50s driven by a Bryston B60R Integrated.  I was drawn to the LS50s because of the coincident/coaxial driver design which works well in nearfield listening situations. I did find that speaker placement and room treatment (back wall, in particular) to be important in achieving the balanced sound I was looking for. 
I agree with the recommendation for room treatments from GLK. Would be a worthwhile investment. If you still find the sound to be bright, I would think about home trialing a speaker with lower bottom end extension and a soft dome tweeter — Buchardt S300.  Free return shipping if you don’t like it.

Any comment on the Wilson TuneTot review by HiFNews?

....In reflex mode, bass extension is limited to 73Hz (–6dB re. 200Hz) and follows a whopping peak at 113Hz (+8dB re. 300Hz).....
There’s a low-level resonance at 3kHz and the familiar high-Q 15kHz dome resonance from Wilson’s tweeter....

Sorry, only saw your post now. First of all I would tell you that I don’t believe in reviews and numbers. My room acoustic is different, my electronics are different, my hearing is different from yours or anyone else’s for that matter. I have had speakers that sounded great at a dealer but performed ghastly in my room.

I would also question the validity of a graph based conclusion. What is a good frequency response? What is the ideal one? Do you think a speaker measuring  perfectly flat would satisfy you? Probably pro monitors and DACs are closest to this target. How many of you use them?

Last but not least I would question the measurement itself. What room? Anechoic or some of those anomalies could be secondary to room modes? How much time did the reviewer spend positioning and time aligning the speakers, being aware that WA are quite directional and sometimes it takes months to find the sweet spot?
