Where would you go after Wilson WP7?

If you like wilson, then obvious choice is sasha, it is a great improvement from
w/p series, maxx would be to big...

THIS! It's easily the
most logical choice. I've heard the WP7s and Sashas in extended auditions. The
Sashas pick up precisely where the WP7s leave off, with more realistic tonal
balance, truer midrange, tighter bass, better dynamics--you name it--at about
the WP7's original price. It's a big leap ahead in coherence, which was always the
W/P's weakness compared to the rest of Wilson's line.

Also +1 about the Maxxes. Way too much speaker for a 16' x 9' room. In fact,
your room size is borderline Sophia/Sasha territory. The Sasha W/P will give you
everything you're looking for. It's finally fully competitive with the Maxx and
Alexandria in terms of cohesiveness and overall goodness, better suited for a
room this size.

I think auditioning a new per-amp is a prudent choice. Certainly the least on the wallet. I have always admired ARC , as i did the original Krell amps. Will give that a go first then if not satisfied go for another full range speaker. Auditioning speakers is a tough proposition when there are no high end stores any more. No one in Atlanta carries ARC, there is Classe and Mac. any opinion on these, I do admire Mac.

The best Wilson setups I've heard were driven by VTL, ARC, or D'Agostino electronics through Transparent (Opus) cable.

Get a turntable and some vinyl

the OPs question was "Can anther speaker sound better given the smallish room?"
