KLH model 9 electrostatic Speakers

I love KLH 9's. I did notice an improvement upgrading the power cords to twisted silver over copper conductors with braided shield for the ground connections. Replace ALL rectifiers and capacitors. Rectifiers should be high speed silicon variety. Check and upgrade all connections points, silver or gold. These are 50+ years old most likely. They sound fantastic even compared to newest technology.

Mijostyn, it blew me away the KHL 9 diasappear, yes , it’s all music, no speakers.Very dynamic.This KHL 9 are own by The late Dr Close, they are in very good shape, He modified the power supplies.The sons are so nice to deal with.

Fiesta 75 , when I have my Martin Logan request , MIT z cord did improve the sound, and a regular Kimber pc , also did improved it, Can I just use an ordinary 2 prong pc? 

Fiesta 75 I have Viva integrated 17 w , I use to used this amp on my Andrea Eggleston 87!db speakers on low level volume, can I try to use it on my KHL 9 speakers too?

Fiesta Viva 300p is just doing fine on the nines, lovely music is coming out of the nines, the volume is set Between 9 and 10.
