Speaker suggestions at around $30k

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.

Adam speakers. Had I the coin I'd be auditioning speakers from these folks (NY). Cannot recall which model I heard at show here in Atlanta, but it was fabulous. Internal powered sub. IIRC, had all the attributes for which you are seeking. They were driven by Accuphase, which I assume helps.

I would get the legacy whisper with hurricane amps, and the updates by vh audio using v_caps. Stock the whisper when amped right is world class and will do rock to classical with a huge panel like stage but with dynamics and good slam. Upgraded, a lot of very expensive speakers have trouble keeping up. And, no I am not a dealer or selling a pair. Jallen
