Floor standing speaker recommendations new or used, $10,000 and under

I did the same thing, tried the salon 1, salon 2, Usher be20dmd, kanta 3, all good all different.  My rooms difficult in the bass so what I ended up with won't apply to many. good luck, they're all good at that level used just different.

Ten grand is enough to get you there if the components are up to the task. I had a chance to own a pair of Vienna Acoustics ‘Die Musik’ for $10k and when I pm’d owners and asked if they thought my components would be a good match I was told no, even the seller risked losing the sale to tell me I would need to upgrade my system for those power/current hungry speakers if I wanted to hear what they were capable of. 

After posting on every forum I could find and reading recommendations for every speaker under the sun I just started buying and selling anything I could afford locally. I got to own several speakers that list over $20k and really learned about my listening room and my personal preferences, that every speaker is a compromise. The ability to own a speaker for 8 months which for me was how long it took for the infatuation to pass and start hearing the flaws, and because of my room bass was predictable with no port support only rear ported or sealed box would reach 50 hz. 
My favorite $10k or less was the Usher Be-20dmd with my only nit being a flat soundstage, wide and deep as you can imagine but not much height to it. Ultimately I combined my speaker and component budget and bought a clean pair of dsp 8000.2's, cured my bass problems and everything else. Happy hunting
