Power Cable Break In - Such a Change!

@jpeters568

There variables measured like inductance and resistance are gross characteristics. There are at least a dozen or more of variables involved and the impact is dependent on the source component and the receiving component, which then impact the output. All of high end audio is like this… as well as the design every single sub component influences the output.

Watch the video earlier in this string… he explains some of the reasons for differences. It should answer a lot of your questions.

Anyway fifty years ago when I got into this pursuit I learned that: 1) cables, interconnects, and power cords can make a huge difference, 2) there are not a list of known variables that you can look at to determine how they will souns, and listening in your own system is the only way to know.

By the way I was trained and worked as a scientist for a decade and I very quickly go… ok, science does not help here (it does for making them… but I am sure it is still largely trial and error with materials),

@ozzy yeah but… I was responding to @jpeters568 question of why can/t it be measured and shown.
I provided the simplest way that I would approach it.

You are seeming to suggest that the question of @jpeters568 cannot be answered with measurements and can only be done with ears. Did I capture that correctly?

Most of my front end gear (old and new) use outboard power supplies that convert the AC.to DC. So I would doubt that there is a effect on the DC, but it could be measured I suppose.
(The power amp is where I would expect an issue could exist.)

@rodman99999 Nice list !!

Thanks for all the posts thus far. Just a little of history. I have owned several iterations of PS Audio power plants. I also have owned Acoustic Revive, Shunyata, Purist, Synergistic etc. The AudioQuest Niagara 7000 has been the most impressive of all of them.

Ahh...Forgive me Ozzy for asking a question you had answered already earlier. For some reason I missed it? Due to old(er) age I suspect?!

@ghdprentice

I didn't ask for anyone to measure the cable inductance, impedance, or resistance, I asked for a mic to be setup in the listening position, record cable 1, vs. cable 2 with all other things being equal. Maybe those who believe cables are awesome are right and the way cables have been measured are indeed all wrong. But for the differences described by using high end/ costly cables, by users who say you have to hear to believe, they claim there is a clear, audible difference in sound, which, should be easy to measure with this test. Null the recorded similarities, and present the differences between the cables from the same listening position, music, etc. 

And with all due respect, when you suggest science can't do something, after being trained in the filed, WTF do you believe in when science doesn't have an answer,  witchcraft? 

This is a SUPER simple test. Null the same things, present what is different. Don't measure the cable per se, but rather, the FR at a listening postion, all things being equal. Yet, not a single cable manufacture does it. Scientifically speaking, should I just believe the guy who claims a 4k cable sounds so much better, and it can't be measured, or, believe in other scientific, peer reviewed studies, about confirmation bias and why the person who spent 4k on a cable may believe it's better than just a $10 one?
