Effects Of Power Cords On Electrostatic Speakers

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.

@roxy54 

Don't mean to be condescending but you and some others perceive that it does.

The only way of being sure is a properly staged double blind listening test.  These are difficult but not impossible to arrange.  Just changing a power cord is not hard or slow, but with powered speakers is the residue of 'old' electricity remaining in the speakers' capacitors will not allow a clean quick changeover.

Just for the record, have you experienced sound differences from changing the power cord to a turntable motor?

As an update. The stock ML cords have been installed on my subwoofers. So I let the system play all night on a playlist. I sat down for a bit before heading out to work. I was able to swap cables between subs and the ML. Small differences between the stock and the Pi ones. Small enough that a new sweep of the DSP program could conceivably minimize those differences even more. I will try that this evening.

But at this point it does not seem plausible that this is a good place to invest any significant money.
