itzhak,
You are absolutely correct. The 300 would not be correct for my size room, and the salesman dutifully pointed out that the PL200 II would be the proper speaker. And again, they were still too analytical for my tastes. I am surprised to hear that the PSB T3's share that same trait, as the reviews seem to mention their warmth.
Thanks for the other recommendations. I will see what I can do to possibly audition the Proac and Bryston you mention.
I did get to spend some time at the Salk production facility (local to me) on Christmas Eve afternoon, and was extremely impressed with their Song 3 with the new beryllium tweeter. Really superb, accurate sound without being dry or analytical, with great soundstage, overall presentation and huge dynamics (hard to imagine for the size). Also an amazing value for the money, not to mention the cabinet finishes were simply stunning. My first experience with Salk, and it has certainly given me something to think about.
