Effects Of Power Cords On Electrostatic Speakers

A better choice for ESL’s are regular transformer-coupled tube amps. Their output trannies provide isolation against such low impedances.

@bellemusique : I suggest you become better acquainted with technical knowledge than relying on hearsay from the "golden ears" crowd!

1.   My CLX Anniversaries came with pretty heavy trick expensive looking power cords.  They sound wonderful to my ears.  What I say is substitute them with regular 12 gauge and see if you hear any deterioration.

2.   OP says he substituted the trick cords and listened.  But the big capacitors in the speakers will have stored the 'low quality electricity' and it will last a while before being replaced with the 'high quality' stuff.  So if he heard an improvement immediately, he was still listening with electricity from the regular wire.  Must have been expectation bias.

3.   There is no scientific evidence that power cords can change the nature of electricity.

By the time the OP switched power cords his ESL's were fully charged. So naturally they sounded far better than initial turn on! Nothing to do with the power cords!

@clearthinker ​: what is 'low quality' electricity? Why do you say that it fills a capacitor first before 'high quality' electricity. So you've invented a new phenomenon for the "golden ears" crowd to obsess over!
