KLH model 9 electrostatic Speakers

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.

I'm happy for you!

The type of power cord will not effect the sound. It is only there to charge the electrostatic panel. Don’t call David Janszen and ask him about it, he will laugh at you. I own the Janszen zA2.1 speakers.
