Best bookshelf speakers


I’m building my first high fi system after being more of a portable audio person. I want to start with the speakers. Space is limited so bookshelf speakers are a must.

Preferences:
Balanced and revealing with a hint of warmth.
Midrange most important to get right over highs and lows
Timbre is super important - I listen mostly to acoustic music especially jazz
But I do need some bass as I also listen to some electronic music
Smaller is better but SQ is most important
A speaker that sounds good with different amps but also scalable with high quality sources
Wide sweet spot - I wont have money for a great amp at first but want them to be scalable for later

These speakers have caught my eyes - any thoughts on them?

Ascend Sierra 2s - Ribbon = dispersion limitations?
BMR Philharmonitor - See above. Also massive.
Buchardt S400/S300 - Wary of the sudden hype train and limited info
Silverline Minuet Grande - Limited info
Reference 3A De Capo - This caught my eye as a potential endgame speaker if I could blow up my budget a little. But concerns about BE tweeter as well as some potential snake oil stuff (cryogenic treatment (!?)), exaggerated sensitivity claims and wonky measurements put me off.

What else should I be looking at?

Edit: I could have sworn I had <$2,000 in the title... Anyway, my budget is 2k.

For < $2k you can try Legacy Studio HD, https://legacyaudio.com/products/view/studio-hd/ . They have good reviews and legacy makes good speakers.
People are still talking about and recommending LS3/5a speakers 40+ years later. Says a lot.
As the happy owner of Sierra 2's, I'm not aware of any vertical dispersion issues.
