Did not intend to open the nonoise must have been referring to in the first reply. And I have no expertise to say anything about this issue.
I would just re-state that it seems impossible to assess SQ differences that are separated by days. And it would seem that this burn-in process, if it exists, would occur over time and not at once....which would make a significant subjective evaluation even more difficult.
And again, why would a cable maker sell a product that is not ready for the level of quality expected by the high end audiophile? If quality is truly that important the cable should be burned-in before it is sold. No one has mentioned any cable maker doing this. So if the phenomenon is real, and I have no basis on which to deny that it is, then why wouldn't a serious boutique cable maker do the burn-in before sale?
geoffkait, it seems rather one sided to demand both subjective and scientific proof from shadone in regard to minor tweaks which by definition would be....minor.... And in fact, it really isn't logical at all to demand "subjective evidence". That's a bit of an oxymoron, no? And in reality, there does not seem to be any "scientific evidence" in this matter at all. So you are asking for evidence that doesn't exist.
