Power Cable Break In - Such a Change!

My ears are my best measurement.

The point was that they are not a measurement. It is called a subjective experience.

The questions was:

I don’t understand, with the descriptors often used for cables, how we don’t have clear measurements showing the “dramatic changes” users report hearing. I’m not suggesting testing the cable, but rather, testing the sound of cable 1 from the LP, and then contrasting that with the sound of cable 2 measured from the identical location? It’s easy to eliminate the duplicate sounds from both leaving just what has changed. The tighter bass, or the better/ different midrange, or airier highs, etc, should easily come through, right? 
 

So, why hasn’t that been done? Why has no cable manufacture shown this? For that matter, what proper test is there, video, showing people clearly able to identify cable 1 from 2? Especially considering there is “such a drastic difference?” Especially considering one cable can cost 10 bucks vs. 4K and more? 

…

Don’t try to equate flowery words, trustworthy ears, marketing jargon with people wanting to understand if something is happening, and then what it is.
The opening sentance started out with “I don’t understand …”, so I guess your point was that the person cannot understand with having the golden ears?

holmz,

Would you prefer equipment that measures well or sounds better?

Both would be ideal.

I could picture a power cord possibly helping with the power amp, but I doubt it would do anything on the preamp or phono stages I have.

But I think it is better to sell the power amp, take the money I would piss away on a cable, and just go and get a better power amp.

We should be able to make a list of what amp sound better with a power cable and which do not.
Maybe we should do that? And then people can buy the gear that generally doesn’t benefit from them?

This is what I posted previously.

"To me the biggest improvements in my system have been with the AC power. That is the usage of dedicated lines, quality outlets, wire, grounding, power conditioning and the power cables. Get the foundation right and the audio equipment can perform at its best."

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),
