power cord for electrostatic speaker

I will say this (keep in mind that I am not a big spender when it comes to PC , SC or IC ):
From my experience with ML Aerius I , I can report that both -
a) power cable
and
b) upgraded power outlets
did improve the sound.
How much of an improvement ?
Enough to justify the cost of cables (Kimber Kable 10 X 2 , show demo = $220) and power outlets by PS ( X2 , $100 ) .
So, was a little over $300 worth it ?........ IMO, Yes.
If you can't hear the difference , just return the cables
and enjoy the music.

P.S Tweak1 - it should be $869.

You just saved 6 big ones here&now.

I can hear the difference also with aftermarket power cords on my ML Aerius i's. I am currently using TARA Labs Prism Special AC power cord. The stock cable is fine, but once you find the right after market I think you will hear the difference with the stock sounding a little congested. I use to have an ugly green pair of Straight Wire power cable that I thought sounded much better then my Prism Special's.... I wish I never sold them.

How can you explain the effect of power cord on the sound of electrostatic speakers? Power requirement of electrostatic speakers is almost zero.

Power is their main source of energy.
From my experience, ML are very sensitive
to any changes in the system and that goes also for
PC cable, PS outlet, isolation from the floor
(cones, spikes, platforms, ISO-Pads etc), toe-in, power quality etc.

I own my Aerius I for around 7 years now and have
pretty good idea how to get the most out of them.
However your findings might be different.
Only reporting my observations from my older system, setup & room.
