Looking for suggestions on best small footprint speaker under $4K

Sorry for the slow response, but have been visiting my new granddaughter this week.   Thanks for all the feedback I truly appreciate it and have a lot of research to do.   I have never bought used speakers though I willing to as long as I can see and hear them first.   
Russbutton certainlynot hell bent on spending $4K,  I have been using a tube amp for the last seven years and really like the sound character.   I just bought a recapped Krell amp and have been blown ay by the sound.   My next amp will be a high powered tube.

Hi miamiangler,  if you are in Miami. contact me

Miami, everything you are saying(small footprint, jazz/light rock, tube amps) points to Totem, I'll add to the other Totem recommendations.  The Totem Hawks are really amazing.  They pay attention to every single detail from the density of the mdf, point to point crossover wiring instead of circuit boards, silver plated internal wire(different wire for each speaker in their line up), even super expensive WBT 0763 speaker binding posts.

Look up the WBT's, and while you're at it, look up the woofer they selected for the Hawks, the Scanspeak Revelator 15W driver.  This is a 5.5 inch driver that can hit down below 35 Hz with Totem's modifications.  Everything they do with this speaker is music first, not sales or profit first.  You gotta try this speaker.

I've had several of their bookshelf models right up to the Sky, which goes for almost $2000 but this Hawk model eats it for lunch in every way.  

Dynaudio Contour 20 or Special Forty.
