For classical music, ranging from solo, to chamber, vocal, and orchestra, I am extremely partial to the entire Austrian line of Vienna Acoustics, which like the Italian Sonus Faber, is imported by Sumiko Audio. I listen mostly to classical, and I have recently acquired a pair of Vienna Mahlers, which I absolutely adore: deep and tuneful bass, authority, subtlety, rich harmonic content, extended silky highs. The characteristics are shared by the entire family of Vienna products, and I just noticed there are a couple of Vienna Strausses on Audiogon--the Mahlers barely smaller brothers: e.g.

This pair is being offered at $2900 (an absolute steal!). Note that Vienna speakers are rather sensitive to placement for optimizing bass control. The relatively generous size of your room would be perfect for the Strausses. My friend and fellow Agoner PSCIALLI fell in love with the Vienna sound at the last RMAF. He rapidly caved in, and replaced his B&W 803s with a pair of Strausses for his 13 x 15 music room. The only caveat is that Vienna speakers like to be driven rather sternly by amps having high damping factors, or they may sound loose in the bass. What is the damping factor of your Aragon 2004?
If you are seeking a set of speakers that make violins sound like emotional instruments with a soul, rather than fizzy/tizzy/stealy creatures, Vienna speakers are definitely worth considering.
