In Reply to: RE: Why do electrostatics sound better after the high voltage has been on for a while? posted by Story on March 15, 2021 at 04:02:58
Hi Story, Kentaja, request for picture I got a laugh at. I'm not done with them, but I shake my head when I look around. This is how I'm listening to my KLH Nine mono.
I'm waiting on high voltage wire for the other speaker, supposed to arrive today. Regarding other component warm-up, equipment with the exception of DAC and turntable is tube, but I listen on average 8 hours a day, and know what to expect. Whatever is happening with the Nine is something else.
Given the age of the panels there could be some issues. Perhaps not enough to impact sonics or overall performance but enough to impact the power supply and time to full charge.
Panels that are not fully charged will sound different after reaching full charge. There might be a small leakage path somewhere and this will slow things down.
Or perhaps aged components in the audio circuit?
It can be hard to determine with electrostats of this age when everything is still original exactly what is going on. Time and high voltage has taken its toll. Usually the panels and high voltage supply are the areas of concern.
I always wonder if it is me, I will try a new piece of equipment and sometimes I like the sound better and better the longer I listen.
Regarding high voltage, I have an electrometer hooked to the speaker and have also checked the voltage at each panel. From what I have been hearing I was expecting to see the voltage creep up, but it is stable. The electronics in these is very simple, voltage multiplier for HV and transformer in the signal path.
I'm still laughing looking around, no wonder they call this an asylum. I had a friend, first time his GF was at his house, "Why do I feel like I'm in a pawn shop?"
wow, that's some really nice stuff you have, and a good reason to hang here at the Asylum. I haven't seen a pic of the 9's in a long time and yours look fabulous. I wish you well at dialing them in.
I seem to remember someone here or somewhere who had the 9's inside door frames of a room for isolating the rear sound waves for better bass, but I am certainly not recommending that.
