Seadweller,
I think a larger model ATC might meet your described needs.
Second hand you can probably find something around $5k in a passive 50 (or 100 if you are lucky), or you could go for the new 40's. ATC's are even better if you can afford active (add to your budget what you think you can get for your power amp second hand).
(Disclaimer: I own ATC so obviously I am biased. However, based on your described needs ATC honestly does fit the bill. They go extremely loud with lots of dynamics (little compression),a very tight accurate lower end and a mid range that is highy regarded by all. So I am not wasting your time by this suggestion. Not just another mindless plug for a my favorite speaker but reasonable advice)

realize it would be impossible to find a loudspeaker with the dynamics of a horn, midrange of a planar or electrostatic, and top to bottom detail of a superior conventional design, but I would imagine some speakers come close. I'm not talking $50K+ speakers, but speakers in the $5K range.
