Best bookshelf loudspeakers under 10,000 for the pair

Quads are a very tough act to follow. Aside from their articulation and freedom from coloration, imo much of what they do well comes from their dipole radiation pattern. That spectrally-correct rear radiation is imo quite beneficial given proper setup.

The little MBL 126 comes to mind, though I’m not sure low-powered Pass amps would be adequate.

Boenicke was mentioned, and while I have yet to hear a pair, their somewhat unorthodox approach makes sense to me.

And I have ALWAYS been impressed by Fritz speakers at audio shows.  

I have a few questions, if you don't mind:  

Will your new speakers be placed on a bookshelf, on stands, or somewhere else?

If they will be placed on stands, will you be able to pull them out into the room somewhat?

Roughly how large is the room?

How important is sweet spot width?

If acoustic treatment (perhaps diffusion) is called for, would it be feasible? Thinking about how to set up MBL’s in a small room...

I need to hear me some Fritz speakers. Seems like they are mentioned more than anything else when it comes to monitors. 

I would buy the persona b and decent stands, buy I may have mentioned that already.

Looks like the Focal Diablo Utopias are on sale. That is one sexy speaker IMO. 

The Fujitsu TD-712z mk2 fits your priorities of "fast transient response, detail/resolution, and musicality" perfectly.  The first two are their strengths and I believe they were designed with them in mind.  Check out the design briefs on their website.  Pair them with the matching sub and you will have an incredible system.
