"Absolute best" used speaker for $8-10K

I would vote for the Nautilus 800N because it has a wide freq. range. And it had the best look of all the speakers in this range. I can give the right proportions of voices and instruments. It gives a very good image of a recording. Just take a change to listen to them. It is one of the few "big" speakers who is capable of giving the intimacy of a very good small monitor. When you listen to recording with only a few instruments it can blow away almost every speaker. I done this tests with many popular speakers in this range. Listen and you'll understand

What kind of equipment do you have at this moment? Because when you want to buy a loudspeaker of this amount you will need the right stuff.
