Upgrading wall outlets

"I am sure a chemist could prove by analysis that there is no significant difference between wines and those who claim the opposite are fooling themselves."- Stanwal

Robert Parker has a working memory of hundreds of wines, and he can identify them in blind tastings, and has done so, thus refuting your hypothetical--and in fact, unlikely--scientist. A moderately skilled oenophile, far below Robert Parker, can at least distinguish wines--if not name them--in blind tastings.

Cable, cord, and socket connoisseurs, on the other hand, reject blind tests, b/c blind tests never show that they hear what they say--and indeed believe--they can hear. That said, some of my best friends are cable freaks.

Shadorne, thank you for your careful explanation. But what, exactly, constitues this "unreliability" of high end audio power supplies that you mention? And how would simlpy changing a household power outlet cause a significant change to the sound (via a change in output to the speakers) from said high end audio equipment?

I'm not saying that no one ever heard a real difference after changing out an outlet. I'm simply suggesting that the real reason for the change is most likely not (as in almost certainly not) the reason that several of you have stated. Bad contacts, yes. Dirty, oxidzed or corroded connections, yes. Magical power genies, no.

I was only saying that the opinion of someone who had never listened to something should be given its proper value. By coincidence I was looking at the HIFICHOICE for this month in which Paul Messenger points out that in regard to outlets:" I've still found it possible to make quite dramatic changes in sound quality , using numerous usually mutually exclusive techniques of wildly varying prices." This has been the experience of most of us WHO HAVE ACTUALLY TRIED IT. Of course, we simple folk lack the wisdom of those who are able to know without actually having to go to the trouble of listening themselves. They live in the world of Aristotle and not of science where pure logic can tell you what will happen without messy experiments.

This thread is a hoot I must post the following short reminders...

...all amplifiers sound the same...
...all cables sound the same...
...all (insert ignorant statement) sound the same...

AND: ALL DOUBTING THOMAS'S SOUND THE SAME

fwiw: this one's been here for all of 90 days; what more would you expect? They come & they go. We've seeen it all after 10+ years on these boards.
