audiphile power cords


Do upgraded power cords really make a significant difference in sound quality? I have a Jolida 502p that I think sounds pretty good. What do you recommend for a power cord that would make a significant improvement?

Bojack gets my "best post of the week" award...agree or not, it's fabulous. I like power cord descriptions from Pangea and the like as the bombast kills me...it seems that any system without premium AC cords must sound like screaming death bats, and with them the electrons are SO much happier and more organized when entering the labyrinth of fuses, resistors, transformers, the spleen, chokes, filters, etc., that your system will suddenly rise from a cloud of stinking mud fog and fix your life.
I put a pair of 'upgraded' power cords on a pair of electrosstatic speakers once for a friend and all of a sudden, when the refrigerator cycled on, he no longer heard it through the speakers. Not only do better power cords do a better job of delivering power to your coponent - they do a better job at keeping things out.
Ive had a pair of inexpensive power cords remove a chalky sound from some class D monos. Sounded much smoother than the stock cords. Ted
The only thing more entertaining than a cable thread is one of those fights you see in third world country parliaments.

On second thought, cable threads are better.
Mitch4t asked if any component manufacturer has gotten on board with recommending aftermarket power cords...

When shopping for an integrated amp last year ($4500 piece of equipment) I spent some time with a tech from the company discussing my speakers, room, and whether that particular amp was a good choice. After covering all the bases, he asked one last question...did I have any plans to purchase an aftermarket power cord. I said no, just planned to use the one that comes with the unit. His response, and I'm paraphrasing, was basically "good, don't waste your money".

It's just one anecdote, from one guy in the industry, but since Mitch asked...

I won't publish this gentleman's name, as I don't think it's appropriate, but I'm quite certain he's been in a position to test more equipment than I have, so his opinion carries weight with me. YMMV.

As a side note, thanks to my local dealer's in-home demo option I have tried various power cords with my ARC VSi55 (not the unit I'm referring to above, that's in another system), and I could never hear a difference.
