Opinions wanted: 10-30K Speakers for Jazz/Folk


See title, which speakers would you suggest auditioning and how would you describe their sound? Price can be new or used.

Looking for specific recommendations and how you’d describe their sounds ie crisp, warm, whatever. Again I enjoy mostly jazz and folk with nice vocals. If you care to share amps you think pair well or ones to avoid feel free! Please spare me responses on why it’s different for everyone or how my question is somehow flawed, just looking for some of your opinions/recommendations, thank you.

@verdantaudio - Those are some excellent choices (especially MBL). Also, Magnapan.
Thank you for the detailed response  @verdantaudio  

Some more info, room is 14x18 feet and speakers can be anywhere but will be facing the longer dimension. No sub and I prefer floorstanding partially for that reason. I hope to install some acoustic tx, perhaps I will use some software on my laptop or something. Energy usage does not matter to me.  Was thinking solid state but could be convinced otherwise. I really like mids/vocals coming through, as for immersion that's tough for me to say. Anyway there's a little bit more info.  

Can I ask if you have any experience with audio note gear, marten design speakers, or spectral amps? Someone suggested these. Feel free to suggest others or expand on those you mentioned given this info, appreciate your thoughts, I know my ask is a bit vague :-)  
I would presume that $10k to $30k is the quality level you are going for, and your goal is not to spend that amount but to attain that level of performance. If you are in the Seattle area you are welcome to come by and hear first hand why you can do far better than $30k worth of performance for not much more than $10k. Then again you can also spend more than $30k and have nowhere near $10k of sound quality. It all depends on what your priorities truly are and what you are willing to do to achieve them.

When I say $30k by the way I am talking not just speakers but amp, speaker cables, and speakers. Good luck with some of that other stuff, you can spend 10X and not get there. I mean, unless the goal is to spend the money.
