KLH model 9 electrostatic Speakers

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.

I used a 25 watt PP tube amp with my KLH Nines successfully! Now have a Futterman H3 25 wpc OTL tube amp!

Jason , Gordon Holt power requirements recommendations is between 35 w and 75 w, my viva is 17w, ok on low volume, my art audio is 40 w this tube amp gives me more dynamic, extensions and nice bass and slam, Gondon is right.
