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.

It seems you are gravitating to the smaller companies and there is definitely merit to that. I used to own KEF reference from the 90's for many years, but since then had moved on and was not particularly a fan of their more recent affordable lines. I have to say though, the new R line is a completely different animal to the the old ones. I think you'd be doing yourself a disservice NOT comparing whatever your finalists are to the new R3. It is that good. 
How big of a factor should warranty be in making a decision? I see a range of warranties from 10 years to no  warranty. 

Do speakers fail?
I like KEF's (listening to Q150's on my desktop right now), but I think the BMR might be the best deal speaker deal in HiFi. Its like a mini-tower and you won't need a sub. You just need the right space for them as they are large. You will need a good amp, but since these are well below budget you can have extra funds available. I'd check out Van Alstine, Odyssey, Job225, Wyred4Sound, or even a Peachtree 150 or 300 and I'd look used too as you can almost always find great deals. Also for good stands check out the Monoprice Monolith stands for about $100. The 24" would be perfect for the BMR. Good luck.

I believe the Revel M126Be, which is $4,000, has slightly better than the 10 x 1 driver ratio cost you listed.

The tweeters are SB acoustics Be tweeters, which from what I can see around $770/pair. And the woofer is a 6" SB acoustics ceramic which looks like go for $173/pair. So right there you have a 4 to 1 ratio. Now obviously they get better pricing than through OEMs like Madisound, but I suspect it isn't more than 25% cheaper.
