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

If money was no concern I'd buy these speakers: Vandersteen Model Seven II.

If money was of concern the best speaker for my dollar would be: Thiel CS3.7. 

I'm a big proponent of time/phase coherence; what else can I say?

Cheers,

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.
