What is the best USED Speaker Under $10,000

I got to listen to a pair of kanta 3's at the store and first impressions are very good. Dynamic and detailed with bass that favors 70's rock. My couple of reservations are how far out in the room they were placed, 8' from the front and at least 10' from the sides with a 7' listening triangle. My other concern, and it was only a half hour demo after work, was the woofers output... It was exciting to listen to but I got the feeling the drivers were at on the edge without going over it. Definitely worth another listen and possibly my new favorite speaker new or used in this price range.

Yes, at only $2k higher price, the Kanta No.3 are a no-brainer vs the Kanta No.2, IMO.  If you look at the dimensions and specs of Kanta No.3, they are near identical to those of Sopra No.3. 

I do think it may be the case that the W cones of the Sopra may be able to handle higher output well than the flax cones of Kanta.  I see a Sopra No.2 on audiomart for $8k, which may be a screaming deal.

@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.
