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

I routinely (every couple of months) loop the Ayre for a couple of hours when I’m not around. I believe it has a positive effect as others have suggested, it didn’t break anything.  For a few sawbucks that includes the bank! I would make the purchase again given the results, real or perceived.

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.

Personally I find that packing behind my ears with petroleum jelly alleviates minute vibration throughout the ear canal which in turn, dutifully increases my sensitivity to sub 30hz bass...🤯

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?
