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.

When I worked for MFA years ago they had some Soundlab A3 electrostats there. I told Scott Franklin that if you replace the very small fuse with a super large value the sound would be much better.......so he went out to the workshop and got a 30 amp fuse and replaced the quarter amp fuse........It sounded way better, expecially the highs.

EVERYTHING MATTERS. Even the power on your lava lamp.....he he.

My first serious A/B of power cords was on a SOTA turntable back in the early 80s.  I had built a pre regulator (30V) and then a cable went to the turntable where there was a 12? volt regulator then the motor which turned the belt.  The power cord was from the wall to the transformer for the 30V regulator.  The best sounding power cord was made using Mogami wire (one of the few serious wires in those days).  Every single thing in the 30V pre regulator changed the sound including the transformer (I tried at least 4 transformers and they all made the sound different).

Of course, I am making this all up (not).  WE all kNOW that the only thing that matters is the measurements.  How dare we listen to things to KNOW what they sound like

An open mind and an open heart = happiness.   I wish you much happiness.

This is so great.....the handfull of "it cannot make a sonic difference because I think so" objectivists.......come out in full force about power cords and fuses. There are thousands and thousands of posts all over the world about the sonic differences in AC plugs, power cords, getting cords off the floor, fuses, fuse directionality, etc. All these people must be deaf or deluded.....only you handfull of objectivists are correct.......because you will not listen. You clearly know that listening is biased. You correctly know that measuring a power cord results in no difference in measured THD or resistance.....and that this is the only thing that matters. Please people, do not listen to your stereo to know anything about sound. Just listen to the objectivists who do not listen. THEY KNOW WHAT SOMETHING SOUNDS LIKE......because, THEY DO NOT LISTEN.
