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

no concern
Biggest most expensive Focals I could find. Would definitely demo lots of great brands before deciding. Monster top notch amp to drive them with top notch preamp (probably tube). Cost no object Dac. 
 

Concern

hmm. Dunno. Currently considering Focal Trio 11 BEs. Sell of everything but my Dac. 

There are a number of Line Source speakers well worth hearing/owning

My first rule is to never buy new - whether it is cars or speakers. By the time you get them home, you just lost maybe 20% and with cars, by the one year point, 30-40%.

Better to buy them used because you get more for your money no matter what level you are buying at.

Whether that saves you $2000 or $20,000 on speakers, that is money you can put into other elements of a system.

I would have several and an environmentally controlled locker to keep them in.

Dream on dude!!
