Nice system and room. It's nice to see a well executed acoustic treatments. So many of the systems I see (some with very expensive gear) have no or very little acoustic treatment. I really think it makes a big difference.
I'm also a fan of open-baffle planar magnetic speakers driven by tube gear, with solid-state amps on the woofers. I've built a similar configuration with DIY open baffle line arrays driven by a 300B SET amp, and separate open-baffle servo-controlled woofer towers driven with a class D amps.
