A “Tuned” power cord, Huh?


I've heard of a tuned turban, a tuned tuba, a tuned tuna, etc...

Please, anyone, is the above “mumbo” or “jumbo”...or...is there an actual scientific explanation for tuning a power cord?

Thank you.

All/most reputable components are "voiced". "Tune"/"voice" would seem to mean the same.
You can tuna Steinway but you can't tuna fish. I have a tunable power cord on my preamp. It is a Vans Evers "Double Pandora" and uses two sliders on the outside of the cord to tune it. Comes with very detailed instructions on where to put the sliders to acheive tighter bass, more extended highs, etc. WORKS!
Elgordo, what exactly are those two sliders “tuning?” Meaning, is there a change of pitch or how do you tune electricity? The electric pulse, wave, what?

Warrenh, I was in no way implying that the Harmonix X brand PC is a bad (or good) power cord. But, when addressing a link for it in an advertisement here on Audiogon, the site offered no explanation about the so-claimed tuning. Hence, my question above. I am glad to hear the Harmonix is working for you and appreciate your mention of that fact.
Santiago, you're right on that: the website that is. If you're interested, or anyone else for that fact, I can email you the guy I bought my cords from. He'll explain it to you. Or try to, at the least.
Thank you, Warren, I would be interested to know more. (Does this guy belong to our dear Audiogon family?)

Looking in the Combak Corporation's website:
(http://www.combak.net)
I noticed that they offer “Tuning Feet”, a “CD Tuning Sheet”, a “Tuning Record Clamp”, a “Tuning Record Matte”, and “Room Tuning Devices”, interestingly enough, “tuning” is not mentioned anywhere in any of the PC, IC, or speaker cable descriptions. (?) Well, except on the box of the PC.
The word “resonances” does appear quite often, though, so I am assuming that “tuning” is some sort of manufacturing technique (of a proprietary scientific development) they employ which manipulates...electrical resonances?

From many accounts, these products are making folks very happy. Is this “tuning” the reason? Do other manufacturers “tune”?

(The “Tuned Tuna” was a local band in New Orleans back in the 60s. Fame, alas, was not their fortune.)
