What is the best USED Speaker Under $10,000

@soix +1. If you can buy JA Pearls for under $10K, do it. Good luck. 

I just grabbed a pair of Usher BE-20 DMD speakers that list for $18,000 new I got for less than 1/2 price in vgc. BIG. Love the look, 3 days into listening so to soon to judge, I'm enjoying how dynamic they play.

Anybody see the dynaudio C4 for $8800? They are too tall to fit on 1 side of the room so I passed but I would expect them to be hard to beat. 

@steve59 there is a new Confidence line so I expect the prices of the previous generation to crater.

Dynaudio uses 1st order crossovers so the sweet spot tends to be pretty small. They sort of off-set this with a relatively lower crossover point of around 1.8K, but that's still a bit too high to mate a 1" tweeter with a 7" woofer, around 1.4KHz is much better like what Klipsch does. When you are in the listening window they are very very good I agree, but in larger rooms they are going to sound dark due to dispersion issues.

If you like Jazz vocal this speaker will be best with pristine treble out of plasma tweeter.

With high efficiency, it can be driven by 300B SET amplifiers.

I had been happy with larger model Lansche 4.1 since 2007.
