Everything matter in the audio chain. Tests prove it!

Thanks for sharing this. I've been complaining that no one does these kinds of tests, and alas here it is! The performances are quite similar but there's enough deviation there to suggest audibility. Anybody know how long the cable runs were?

Ah, I'm slow at picking up nuance sometimes. Now you've got me thinking about "the measurement guys." I'm envisioning people who own equipment just to measure it - they never listen to it at all! There's nothing wrong with that I suppose if they get pleasure from it. I'll have to admit I've gone down this path to some degree with photography equipment. I've spend huge amounts of time doing test shots at different aperture and shutter speed settings just to see how sharply detailed I can get a picture with a particular lens, enjoying that process more than actually going out and getting good photos.  

If the ears aren’t convinced then the graphs and charts are telling us what we can’t hear or don’t notice as important to our enjoyment of the sound. That’s good information just as much as when the charts and graphs do correlate to what we like. I shouldn’t leave out the potential case where the graphs and charts show nothing but the ears are convinced there’s a difference. Is it the ears or the mind, that’s the first question I’d want to nail down - make sure the ears alone can pick up on the difference when the brain isn’t being contaminated with information about the sound source coming from our other senses. And I'll add that it's perfectly OK to not care why the sound seems so good during a sighted listening test and just enjoy the total effect coming in from all the senses.

the differences will be notably more huge, if one does transient and complex transients stacked and their harmonics, as a fundamental test.

I take it you must know of tests that have already shown this?

I recently experimented with a SOTA power cable from Audio Magic replacing the stock cable and the improvement in picture quality was dramatic.

What kind of image quality improvements did you see? Are they obvious enough that you could take before and after pictures of the screen to demonstrate the difference? On my equipment I have seen the image quality occasionally go weird and had I taken a picture of it I'm sure I could have demonstrated it. In those cases I had to restart or reconnect something to get the picture back to it's normal excellence.
