What used speakers raraely come up for sale

One of my favorites, the Gale 401a, with the chrome end caps.

Agree with the Silverline SR 17,s I've seen maybe one pair here on Audiogon in the last year and the Dynaudio Special 25,s at least 2 years since I've seen a pair here for sale.

Vandersteen Quattro,s  alot more frequently.

The Focal 7v7,s sound interesting.

Revox Agora b, and Meridian M2. Both active systems and superb. 
Also Linn Isobarik bricks. 
I am lucky enough to currently own all 3 pairs. 

Wilson Benesch Chimera..seen for £5k recently, were £24k. Utterly fabulous. I had the Acts for 10years these are way better but same sound signature. 

Diapasón adamantes. For music lovers.
