Stand mount loudspeakers

Room size 15x 12 8 ft ceilings. Undecided about subs. Type of music, all kinds. Price range to $15000.00. System preferences, wide and deep soundstage, Good piano, violin and great female voices and NO head in a vice.

Why are you limiting yourself to stand mounts?  Many tower speakers take up no more square footage than a monitor on a stand.  Totem Forest for example.  As to "all kinds" of music - most people favor certain kinds of music and so do most speakers.   If you are willing to go that high, I would try to score a pair of used Magico Q1s.   They are fantastic when paired with the right electronics.  

One more post in favor of towers/floorstanders - they are less likely to fall off or fall over if there are pets or kids involved. I'm not saying they NEVER fall and there are some that are very susceptible to being tipped, but nowhere near as easy as standmounts (unless the speaker is secured to the stand). 

Standmounts can image better in a smaller room than bigger speakers sometimes.  

Pair them with an integrated or pre with bass management and room correction like the Anthem STR series and a good subwoofer or two and you can have a system that can easily outperform a pair of traditional towers.
