My apologies_Upgrade path from Wilson WattPuppy 7's?

Folks-

I am the naive person who posted about which speaker to buy next, my system is all McIntosh, except for the downloaded high-resolution music content. Since I have price limitations, I have been attempting to audition loudspeakers under $15K, preferably used or demos. In various stores, I have heard the following:

• Vandersteen Quarto CT's: Great bass, but an active system that does not seem to resolve high mid-range strings like a Wilson;
  
• Triton GoldenEar Reference;
• Sonus Faber Venere S and Olympica's, great sound in the store.

Currently, I am auditioning (in-house) Wilson Yvette speakers (it cost $400 for an in-house demo), and they sound great to me, but they are too expensive, even at a reduced demo price.  I started comparing frequency and impedance curves where I could obtain them (mostly Hi-Fi news from the U.K.), but I am becoming too obsessive about this.

So, I guess I could buy the Wilson Sabrina or Wilson Sasha WP (discontinued Series 1), since I seem to like the Wilson sound. Any advice?

Thanks again - Gerry
