Dan,
Thank you for your PM, which is exactly that ....... I mention Pavel as he is one of the few working electronic engineers out there who has the intellectual capacity to understand your line of enquiry. That he is scrupulous and rigorous in his analysis is all for the good. I wish other diyAudio members with similar skills would step forward and help you more. Nothing about audio is written in stone, and everything that we know and understand is in a perpetual state of flux. So collectively, I reckon we should all try a bit harder to understand your experiments.
I get it, (or should I say - the gist of it) but alas, some others don't. ToS
Some people still laugh at Tesla, or at least at some of his dafter ideas. Others seem to have a regard for him not far short of worship, presumably because he took on the 'establishment' even though in some cases he lost (due to being wrong). Science is like that; engineering should be too and is like that in most areas apart from audio and antennas.
The later ideas of Tesla didn't pan out. Frankly speaking, they were bonkers. At the end of his life, he conversed with pigeons. Don't encourage a pathetic relationship with logic and reality. Pavel did not prove him right, he rather found a mistake in his procedure.

This is actually a very good point (better before you edited it 😉)
Is this a healthy response, really?
On my opinion, the problem (if any) is not there.
It is to work on what matters.
If I had understood well, it is an other "cable sound" attempt. Well, as a cable (apart iimpedance) is producing lot less change in the audio signal than o lot of other things, better to concentrate on something with hundred time more influence.
Our speakers, as an example, that have a lot of distortion and non linearities, both in the response & group delay curves and time domain.
As I said, I have listened honestly to those files. With curiosity. First, it is difficult and painful to figure out differences in files with so poor qualities on the technical and/or artistic aspect.
I did-it and sended to Max good files to reveal different aspects of sound reproduction. Good global balance, micro and huge overall dynamic and little détails, quality of the reverb/sound stage.
That the pieces of music I use, personally to test my gears and the progress of my work. Why not to use them instead ?
Second, I do feel some differences. But i was obliged to go back and forth to figure out and stay, following the set-up and the moment, in a great uncertainty. Exactly the situation when I do a blind test listening. That I don't do any more, because, If I can't find a CLEAR difference with 100 % accuracy, I give-it up.
Hifi is supposed to be a way to listen to music. Not a fantom chase or a mystical quest.
More than this, my preferences (If any) varied from a test, a set-up, the moment, from one to another.
While I can find anytime, on any system, the differences between two DACs, by example, why to bother on cables between them ?
For me, it it like to work on the varnish of a formula car during a pit stop.

Exactly. I seriously doubt the setup and experiment which leads to a 25ms drop-out in one case and to short-term audible distortion in second case, both probably due to a bad contact. And the rest of the files is supposed to be perfect???
Spend some time on radio websites and you will find lots of wild claims and confident assertions of nonsense about radio antennas, both from amateurs and some commercially involved in radio. The most common ones involve either denial of charge conservation ('no counterpoise' antennas) or violation of the Chu-Wheeler limit (impossibly good 'results' from compact antennas).shc said:
Tryphon,
I find myself acting as an advocate here. You are right, it is best to concentrate on what matters. What Dan is doing with his experimentation with cables most certainly matters to him, as he sees the results he is getting as part of a bigger picture. Exactly what kind of picture he is reluctant to say, and I understand this. I also agree that Dan is on, as you describe, a phantom chase or a mystical quest. But somebody has to do it, and it might as well be Dan, as he seems to be doing it rather well.
BTW, I am a big fan of yours. ToS
"radio websites". Now I understand. I'm more familiar with the scientific approach to antennas than with antenna-voodoo. My mistake.
Vacuphile,
I never said Pavel proved Dan was right, I said he was trying to help Dan by verifying and correcting the flaws in his methodology.
Next time, try harder. ToS
No, it's just a secret - something you tell other people one person at a time. ToS
As I see it - I am skeptical to the tests that are not perfectly prepared and have basic flaws. IMO no conclusions can be made of them, other than that they have had basic flaws.
I also tried to find a cable influence, in a similar test, about 5 years ago. 12m of a standard cable like Tasker 121 was used. The only influence was some time delay like 70 nanoseconds (funny compared to audio numbers) and maybe some capacitive RC HF roll off (high above audio band), depending on source Zout. I am afraid it is time for me to take a several month break again, as nothing new can be seen here.

Touched, since i'm not a big fan of myself ;-)
I'm not at all trying to be disagreeable to Dan. At the contrary.
But, under the rose, there was a time when I listened to my mixes in loops, returned home at night, looking for the slightest flaw.
Today, I can find others, probably major, that I did not hear at this time, too focused on the details.
Taking a step back serves as a lesson ?
I re-read your post and see that you are right, you posted that it would be great if Pavel would come around. I don't think he did, really.
