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


Hello I'm looking to some new speakers and I need some recommendations to audition.  I currently have the Nola Viper IIa, but I'm looking for improved bass and just an improvement in sound overall.

I have a Mcintosh mc7150 power amp and a De havilland Ultra verve 3 preamp.  My source is a musical fidelity cd player.

I have a medium sized room, approximately 20' by 16'. Ceiling is about 9ft high.

I've listened to the Focal Sopra 2. and the Totem Acoustic Hawk, but I'd like to expand my options.

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. 
In that range I’d be looking at Goldenear Triton Reference, or Tekton Ulferberhts. Vandys speakers are great, though I prefer the 3As over their more expensive models. 
Definitely the Legacy Focus SE's, or the Spatial Audio's, or Emerald Physics options in that price range, before a lot of the others noted.
for something completely different, Infinity RS-beta.  Stunning dynamics, bass, large image.  flawed? Isn't everything?
Egglestonworks Andra MK-I or MK-II 

15K new / 5-7K used

I'm looking at getting the pair in NJ....Full range for sure!
