Wrapping power cords and interconnects with copper foil.

Do you have any photos of the cables after they were wrapped? Also, which brand of copper foil did you use, and were did you purchase it?  Thank you

why are there so many writings that look technically correct, but only the writers' opinions. I did the wrapping to my turn-table cables. just wrap. it really worked. s/n ratio was actually, really improved!!! I recorded the signal after phono-amp into my computer. the computer software showed noise level differences before and after the wrapping (aluminum foil). period. any doubt? please do it. it is very simple. if you are not a computer expert, just volume up while no music being played. you can hear less noise (backgroud hiss). I am not a big fan who buys expensive cables. just do it, then you can realize you don't have to donate your money to expensive cables makers.

I stop giving my experiments results here long ago except in general way of speaking because instead of welcoming each one experience with an inquisitive and curious mind many people gave sarcasms or common place engineering explanation ....

The same people often gave their money in gear upgrade not knowing how to improve their audio at no cost...

Yes i used copper foil and numerous others basic facts and basic no cost devices...

And after their upgrade they are convinced by (consumers bias) suggestion in the same non controlled room that all is better... Then they read about someone making a low cost experiment and they throw sarcasms about their tin foil biases about S.Q. value...

Most audio thread are useless because instead of experiments they spoke about gear...

It is once your gear is bought that begun the audio journey not before or not till an upgrade... It is after you had bought the gear that you must learn how to put them at his optimal unknown working level with mechanical,electrical and acoustical embeddings controls method and devices... Including copper foil....

Congratulation to the OP for his courageous thread at best  facing ignorance, because no ears/system/room react the same way to any  change or at worst contempt by programmed mind with no need for any experiment ...

I just did a search and copper foil is pretty affordable on walMart’s site--$6.69 a roll/free shipping. For that price I’ll try it on my $50 power cords and listen to it, and then I’ll try it on my Kiimber Silver Streaks. If I cannot hear a difference, I’ve blown way more than that on tweaks that I could not hear.

. . . and then there is copper adhesive tape from Amazon @ $9.99 for a 12 yard roll.  I think that might be easier to work with than the WalMart roll.  One roll MIGHT do all my power cords.
