Best speaker on used market around 10,000.00

Eggleston Andra-2 Speakers (used)- two woofers, two midranges, and a Dynaudio Esotar tweeter per channel. powerful but sweet trebles. you should have bought my pair (they were mint). all the good reviews of them should be fairly convincing as well. BTW you can get a pair for LESS than $10K even though they are worth it.

I owned the Andra 1 and did not keep them long. Is there a big difference in the 2?

sounds like you need krell "slam and dunk" endless drive and attack,dynaudio c4 which also have punchy sound ,and bryston source bda-1.Sound which doesn't rip your head at loud volumes and you loose sence of volume you are listening to music

Avantgarde Unos or (if you're lucky) Duos.
