KLH model 9 electrostatic Speakers

I tried my MIT Speaker Cable with a box , I think it’s the s3 , there is no sound coming out from KLH.

I connected my MIT speaker cables with a box to my KLH , no sound came out. The mit works on my other non electrostatic speakers, I wonder why..

I agree mijostyn! After many years with cones and domes planar magnetic the ESL treble is most like live instruments. Trumpet, violin, saxophone etc. I recently picked up the motion ESL by Martin Logan at a great price. Even that little speaker has truth of timbre a $100k speaker couldn't match. I know ML it's not perfect ( slightly lean sound) but what it does well is SOTA!

Martin Logan Speakers are excellent, I have the request for five yrs, this speakers like bass trap on the outer side.

Glad to have found this thread. I've owned KLH Nines since 1972 and driven them with Futtermans H3a and Marantz Model 9 I am still driving the KLH Nines with the same Futterman (recapped of course) and of the 3 pairs I've owned I've kept one and had it refurbished by David Janszen. I donated an early prototype (used 4 large bass panels instead of the 10 now used) I had as well to David as a gift. I drive the Nines with the Futterman or Accuphase. I've heard just about every Hi End speaker made since I love going to audio shows and owned Sound-labs A-3s and as well as still owning Modified zA2.1. Once you listen to a Nine its hard to forget them. The cords to the power supply cans make no difference at all.
