Looking for Speaker Recommendations

Budget: 10k or less.

Sound characteristics: Serious presence but not fatiguing. If the recording is of a good live rock (not metal) concert, I want to hear all echo and digital delay effects, snap on drums, seriously good midrange and vocals, arpeggios on electric and acoustic guitars. 

Sonus Faber… maybe used Olympica.

I am now on my third set. See my systems.

I've got about the same size room and have been very happy with my Aurum Cantus V7F speakers. You might also look at the Paradigm 120H since the woofers have room correction built in.

Spendor D9.

Perfect synergy with your amplifier.  Dynamic, clear, refined and excellent deep bass.  

If you like Wilson, you can pick up certified pre-owned at very good prices. Wilson owners like to upgrade when new models come out and the used ones are usually well priced. There are plenty for sale right now, especially Sophias.
