Effects Of Power Cords On Electrostatic Speakers

@ricevs   Did you seriously replace a quarter amp fuse with a 30 amp fuse?  Classic audiophile idiocy!  And feeding a 12V regulator with 30V means it has to burn off a lot of current, markedly shortening it's lifespan.  But safety does not seem to be your primary concern.  As for hearing a difference between power cables to your pre-reg, I say nonsense.

@clearthinker +1! Unfortunately there are many here that do believe in the 'good' vs. 'bad' electricity fallacy, even to the extent that one needs an 'audiophile' wall outlet for purer voltage transfer.

Indeed!  But what about the 400 yards of cable from the local 8kV transformer to your home?   And the 10 miles or whatever to the power station?

You can't change those.  Why these people think six feet of cable, or a wall outlet, or even a fuse, is going to change all that bad electricity is a mystery to me.  Maybe one day one of them will explain.

So I have Acoustat Model X’s.  (They’re the ones that came with the servo amps built in.) Anyway, As part of the Mods I did or had done, was to remove the hard wired power cord and add a IEC receiver.  I tried a well broken in pc from an old computer and it sounded the same as the factory setup, but when I plugged in a Audience F3 pc and there was very noticeable improvement.

I’m not sure if this helps with what you have,  it it’s definitely worth a try. 
 

All the best.

I agree with you both that there is no logical scientifically valid reason to believe that it will make a positive sonic difference, and yet it does. Some things can't be explained with current knowledge.
