Speaker suggestions at around $30k

I just heard the new Rockport Avior speakers and they are quite amazing! They certainly check all your boxes.

Ditto on the TAD. I've heard them at many shows, and most all the time I am left fantasizing about having them!

I'll throw in the Adam Tensor Betas or Deltas--in fact, if you don't need the last octave of bass, the Deltas should work just fine for you and you'll have about $20K left over. Their highs and midrange are very realistic sounding to me, their powered bass drivers mesh very well with the ribbon-style mids and tweeter, and overall these speakers do a great job (IMO) of reproducing the dynamics of live music. If you have a chance to audition them I would highly recommend it, they may not be your cup of tea but the more I hear the Deltas the more impressed I am by them.

If I had 30K to spend on speakers, I believe I'd start hitting some stores and hear them for myself, but hey, that's just me.

Wilson Sasha's. I just listened to them today. Why? Because of your stated preferences.
