10k system for ultimate image density at 70-75db?

I agree with those who have suggested electrostatics. Martin Logans are worth auditioning. Quite solid sounding and not all airy like you seem to think. They seem to have done a pretty capably job of dynamic woofer integration...

What do you mean by scream? Your Energy's are highly respected and have a great forward "in the room" sound - I don't think anyone would describe these as screaming above 80 db, above 95 db perhaps. If anything the only faults with the Energy Veritas line were that some designs had distinctly too much bass and that the dome midrange is limited in loudness before compression becomes a factor. In your case, too much bass is what you probably need when listening at lower levels (phon curves and all that stuff)...
