The AMPS & SPEAKERS
Stereophile called the KLH 9 the “Best Available Loudspeaker System, Regardless of Cost,"
“The KLH Nine was the first truly full range electrostatic speaker. Even fairly recently, it was declared one of the 12 most significant speakers of all time, and has been written about repeatedly”  - David Janszen, Janszen Audio

The EXTEMELY RARE KLH One bass response: “They positively move the rafters at volume. I recorded 120 db at one point, and that's not all they have.”   
“All this to say there are passages on music I currently play- have heard many times- where the depth of bass is startling. However, it's not boomy, at least in their current position (3 feet out from the wall). And they will get really loud without any effort at all, which means no distortion that I can hear. The sound is tight all the way to the bottom- no apparent bloom. “

HISTORY OF THE SYSTEM
This system was acquired in 1962 and maintained by a single original owner, my father, Clarence C. Close, M.D., in a specially designed temperature controlled hi-fi room.   Dad was no normal audiophile.  He was also an army trained electronics engineer and recording producer.  He recorded classical artists all over the midwest, including Easley Blackwood, Frank Miller, and Van Cliburn winner Ralph Votapek.  His recordings are now archived at the University of Chicago, the Chicago Symphony, and the University of Maryland.   In short, he knew his stuff.  In fact, SHURE asked Dad to test their new record cartridge prototypes on his system.    
In the 1990s he rebuilt the KLH 9 power supplies with better capacitors (published article available at request).  All the equipment has been expertly maintained for the past sixty years.    
The entire system was twice these units plus a Marantz Tuner and Preamp.  We are keeping that half in the family, but offering the rest as a core for a system of true fidelity.    
PRICE: $25,000 and we will deliver within reasonable distance from Chicago, otherwise plus shipping cost.

Questions for the seller
How did your dad cross the woofers over to the panels? Is there an active or passive network?
you'd have to reconfigure. Dad had 4 Marantz 9s, 2 for the KLH ones and Two driving the 4 KLH 9s
