It seems that for every thing that gets mentioned as a tweak/tuning there are two sides. One claims it is non-sense and cannot be true noticeable difference and the other side claims that the difference is noticeable.
That’s actually the false dichotomy that I’ve been at pains to reject.
As I keep arguing here, one doesn’t have to take a single side "it makes an audible difference/it doesn’t make an audible difference" position.
One can simply take the position "I don’t know if there is an audible difference, so let’s discuss the reasons and evidence for why there might be an audible difference, or not."
Being a long time audio-nut myself, and always liking the idea of further enhancing the sound of my system, I'm very attracted to the idea of "tweaking" my system. So it's not something I reject on some weird a priori grounds - in my more tweaky moments I WANT things to make a difference. But I also realize this is also when I'm most likely to fool myself that there is a difference.
