Help Me Explain Power Cables to my Guitar Friends


Guys, I need some help!

I have suggested to some of my guitar geek buddies that they could improve the performance of their tube guitar amps by replacing the power cords. Now, I know that many here already believe in the qualities of upgraded power cords. But I can't convince my guitar buddies; they won't even try it because they say, "You need to show me some scope measuresments before I believe this 'snake oil' stuff about power cords."

Does anybody know of some way you can "measure" power cords that would "demonstrate" that they can improve performance? Help me out here!

Equipment does exist that can measure distortion, rf, emi but you can't find any test results because no manufacturer of after market high end cables will perform one, much less publish it, because the cables make no difference.
if all audiophiles had guitar buddies to protect us from that which is audiophile b.s., the world would be a better place. until someone makes a power cord with inlayed pearl stars, i'll just use what the labs and studios use...a stock cord.
Ask your buddies if they bought their guitars and strings based on scope measurements! Certainly, before I bought my drums, I had to have them measured with an accelerometer on a scope in an anechoic chamber!

If your friends refuse to simply give a comparitive listen, let 'em be ignorant...no skin off your nose.

I don't know if I can offer anything other than moral support. As you well know, many audiophiles have great difficulty with judging performance by "measurements". If we bought according to "measurements", nobody would buy tube amps. People would all have Pioneer receivers with distortion measurements of .00001. No offence intended to the owners of Pioneer's fine products. It is the lack of standardization in measurement methodology which is one of the reasons for this of course. As somebody once said: "Standards are a good thing, that's why we have so many of them".

I would make further efforts to encourage them to actually try it. Do you have a guitar that you can demonstrate with if they won't try it themselves? You can maybe needle them a bit to cajole them into trying. Ask them why they trust measurements more than their own ears. Ask them why they want to be told what is better rather than seeing and hearing for themselves. Ask them why they're so closed minded...suggest that as they get older, they're becoming more like their parents! Middle age is that time in life when one's broad mind and narrow waist change places. Most guitar geeks are a bit of a rebel. These type of sarcastic comments might arouse them to their natural non-comformist state and they might try something just to be defiant. Ask them why they use crappy tube amps when solid state amps "measure" so much better.

And of course, if it does work and they try it, you'd better make sure that you have a power cord that actually does sound better.
Changing power cords might actually hurt the performance of a guitar amp, Unlike hifi, guitar amps are all about coloring the signal, and they are prized for the ways in which they distort.

Many classic sounds are based on undersized power and output transformers, carbon composition resistors, underfiltered sagging power supplies and overdriven speakers and tubes. It's a whole different country.

Guitar playing is my other hobby, and I use a completely different set of criteria for judging guitar amps. As a player it's as much about feel as about sound. "Improving" the amp with a power cord may destroy the qualities cherished by the player.
