Why no “Break in” period?

Prof, I wish I was as eloquent as you are and Simonmoon I believe you are absolutely right. 
Everyone is entitled to their own experience. My problem comes when people try to sell stuff to other people that are less knowledgeable and perhaps more gullible. Companies take advantage of this to sell products that are somewhat more than ridiculous. Then one of us thinks it made his system sound better and away you go. I think the Walker turntable is a very interesting design but I would never consider one based on the other crap they sell on their web site. 

Buy Music,

"therefore my experience has verified the claim and anyone who doesn’t hear what I hear is at fault."???                                          PLEASE, point out any post, in which I’ve ever put forth such a proposition.     I’ve never had an agenda, on these pages, other than to encourage others in listening/experimenting for themselves.

Certainly, you're not saying some are taking liberties with what was said and portraying them as a position that you never ascribed to? That would be unethical. 

At dinner one night, second bottle of wine comes, finish my glass and pour another and.... what the? Sharp, astringent, acidic, had to double-check. Yeah same wine. Wife still had some of hers from the first, try this, sure enough, first ones better. Huh.

Little while later, pour myself some more, now it tastes like the first bottle. Does wine really need to "breathe"? I guess if wine drinkers were like eloquent audiophiles there’d be someone at the table pontificating on how if you say it tastes better fine but don’t go try and tell me it tastes better harumph harumpf.

When in fact after a little more conversation and investigation it turns out the wine does in fact taste better, and I’m not gonna go into the whole story of how we demonstrated this but we did in fact demonstrate this.

Turns out the issue is not after all anything like its being made out to be, however eloquently the illogical dog chasing its own tails narrative is told. What we were able to show is really going on is the difference was there all along. Some just weren’t paying attention.

There’s always gonna be people who aren’t paying attention. Which is fine. Makes the world go round. Only funny thing, pretty much always turns out the more you pay attention the better you do. Which is why I’m always recommending people go and listen. To DYODD. To listen and audition and buy what you like and not what some random interwebber recommends. Over and over again.

To disregard the vast number of times I’ve said this, well that is beyond not paying attention. We’re talking downright willful ignorance here. And for what? To make a cheap audio turf war point?

Nah. Couldn’t be. That would never happen. Would it?

3. What prevents whatever the breakin process is, to stop when the equipment sounds better? Why doesn't it continue to breakin for its entire life and continue to improve?

Can you step into the same river twice?
Can you listen to the same cable twice?

"Break-in" is a difficult thing to accept.  The word "aging" is more universally accepted.
