Gray, I simply don't understand the relevance of this comment. I honestly couldn't give a monkey's precisely what was 'doing the jumping'. I happened to make this one minor change to the set-up and it sounded like a major improvement. And yes, it was my ears that noticed it (and also my wife's!) - are you suggesting that for something to be subjectively noticeable, it has to be backed up by repeated A/B comparisons or even sophisticated measurement?
Or perhaps I'm in the minority in believing that if my ears tell me it's loads better, that's good enough for me?!!
If you were to tell me that subjectively
your ears might not be able to tell you if your sound has improved, I'd be most surprised (possibly even 'astonished'
) - surely subjective improvement is what we all try to achieve if we're remotely bothered about how our hi-medium-or lo-fi entertains us.
The bottom line is that my small experiment produced an audible improvement to my listening pleasure, whether or not you believe it! The ears have it...
