OK...here's another tweak that really works

It’s fine to discuss the merits or lack thereof of any individual product, but why the character assassination? I suppose judgement fits need to construct human hierarchy pyramid with them on top

While I tend to agree with @jasonbourne52 most of the time…
There is possible some science that could explain what the disc possibly is doing. (!) <— @nonoise

Interesting!  Burn-in with noise is better than with music.  Why?  Is there scientific proof? It is like breaking in a brand-new vehicle with harsh rather than gental driving behavior.

There are those who can not accept a product unless it makes perfect technical sense. I respect that, but experientially if it works, then why not enjoy the ride instead letting the lack of logic be a barrier. I personally like to know how a thing works.

It is better if it can be shown to work either with measurements, or * blind listening tests. Then one can know that it works, even if there is no logical hypothesis to explain it.

I also like to make improvements in my systems where I can hear things that I did not before, see a more defined image, feel more connected to the sights and sounds, etc. To me the experience trumps the logic.

Once we “see” a device, we then also expect a difference.
That creates a bias of expectation.

We logically believe that it is (or should be) different, and we then experience it as different, even if it is not different.

We may have to agree to disagree on some points. I know there is always a psychological element at work, but if you have been around a lot of live acoustic music, played an acoustic instrument or been in the hobby for an extended period of time, then I do believe you can develop an 'educated ear' and can reliably tell the difference between something different versus something better. I think where the confusion often comes into play is when there is an overexposure taking place such as going to an audio/video show and visiting dozens of different rooms. Even so, though, I still believe that even in an environment like that an experienced audio/videophile can reach some valid conclusions.

So for me, I pretty much trust my eyes and ears knowing that not everyone would agree, and that's OK,

That may all be true, but the psychological element is well studied and documented, so it makes it easier believe that these things are likely based in psychology versus based in reality.

If we want a way to remove the bias in believing it is all psychology, then how could we do that?
