Effects Of Power Cords On Electrostatic Speakers


Several weeks ago I took delivery of a pair of Martin Logan CLX ART speakers. I hooked them up with the supplied power cords from the seller. The sound was pretty underwhelming, so I let them settle in. After about 4 days the sound had not changed significantly. I decided to rob a pair of PI Audio power cords from my phono stages and put them on the CLX. Signicant change and was getting the sound I expected. 

The question I ask myself is why? This is a low current power supply that just feeds the stators. 

If it is indeed significant, and it seems to be, what level of cord is going to meet the needs? No reason to spend more than I have to. 

 

Looking forward to reading your thoughts or experiences.

You can make up all the reasons you want, but the truth is you heard a difference because you wanted to hear a difference.  Just like the people who hear a difference when they "upgrade" the power cord on a turntable.  What's next?  Upgrading the power cord on your lava lamp?

@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.
