Power Cables and Wall Sockets

"The former case is a more of testamony like the Thomas (or what it another fellow on the road?.) The cable makers could show something happening with out just resorting to talk about the quantum world.

It was St Paul on the road to Damascus who had the revelation.

'Doubting' Thomas was the apostle who did not believe Christ had risen from the dead after being crucified until Christ showed him the nail wounds in his hands.

Query.  If Christ could be brought back to life after being dead for three days, surely cleaning up the nail scars would be trivial?

"Without knowing for certain, it seems to me that power cables can only be as good as the in-home wiring coming to the wall socket. "

That's the logical conclusion.

Like many others you say the last six feet of passive cable can make a big difference.  How?  Why is the last six feet different from the five miles or whatever of cable from the power station to your home and all the transformers, joints etc etc on the way?  Please explain in terms of physics how a passive cable can do this, absent active components and power conditioners that certainly can affect the quality of the power we receive.

Thanks @ghdprentice 

Like many others I am inclined to put even quite large perceived sound differences down to subjective hearing and listening issues, mood swings and expectation bias when they are engendered by changes of passive components like power cable, fuses, cable lifters and the like.  I am made more sceptical by the fact that such changes invariably are percieved to improve the listening experience rather than diminish it.  Not like a virus mutation at all, which is random and just as likely to ameliorate the effects of the virus than worsen them or, perhaps, to ameliorate some and worsen others.

But please let me enquire more into your experiences if I may. I am guessing most of your positive perceptions arise on changing the power cord of electronic components such as CD players, DA converters and amplifiers?

Some say they have perceived positive changes on switching power cords to an LP turntable.  Have you?

Or power cord to an electrostatic speaker?  My Martin Logan CLX Anniversaries came with very exotic expensive lookin cables - quite long too, about 10 feet,  Am I getting value for what I paid for those?   Electrostatics don't pull down much current, especially once the initial charge is completed and they are just being 'topped up'.  Thinking about that, could the electricity supplied by the exotic cable to power up the speaker initially continue to improve the sound afterwards?  But that situation is analogous to that in a big monobloc.  The amp draws power on switch on that is stored in a huge capacitor.  Once stored can it really retain the enhanced character that it acquired from the 'high-end' supply cord?

I have a pair of old Audiostatic speakers that are powered by fixed manufacturer supplied cords not much heavier than bellwire.  But the speakers sound pretty good.  I had them 20 years or so before buying the Martin Logans.

I am beginning to become intrigued enough to power down the Martin Logans, let the charge die away over a week or so, then power them up again with such bellwire and see if the sound changes once they are fully powered up again.

Down the rabbit-hole......

What do other people think?
