If money was and was not of any concern when buying speakers.

Money being an issue: the speakers I currently own, a pair of Dali Zensor 1 (bookshelf) and a pair of Zu Audio Omen Def (floorstanding). Both deliver a sound that truly satisfies me and both were acquired after many hours of listening and comparing (within my budget).

If money was not a problem, a pair of Harbeth bookshelf and the mighty B&W 800 Diamond! 
The B&W was the only speaker that fooled me into thinking that I was listening to a live concert before entering the room where they were playing. Matched with the right electronics, of course, that I can't recall what it was.

 I recently visited a magnolia design center where they had big mono block Mcintosh amps pushing 800 diamonds. It was musical bliss!  

The speaker I would buy for myself if I had the bucks would be

Muraudio PX1 Omnidirectional Electrostatic Hybrid Loudspeaker

at $63,000.00  the pair.   Oh,  how I wish to own these.

Money no concern: I’d probably second the choice of Living Voice’s Vox Olympian & Elysian, given the listening room can accommodate them properly - which hopefully wouldn’t be an issue with monetary carte blanche. Battery-driven amps and source, of course.

Money a concern/practical consideration: what I got now - Simon Mears Audio Uccello. Only "tweak" I’d consider here would be, sometime in the future, adding a horn sub (LAB’s or otherwise). That, to me, would be the budget version of above, and as is (i.e.: without sub) is richly rewarding already.

Financially out-of-reach as is, the "in-between" alternative of interest: Sadurni Acoustic's Staccato.
