Flyski, Why would anyone bother to go thru all of that just to prove a point to some one who sez it doesn't happen, or that it can't happen, that it's all in our head, or at their most gracious have never heard it themselves. Frankly IDGAS what other's can't hear.
Personally, I break-in new equipment while leaving all of my original stuff in place (or in a different system) and do not listen to it constantly during the process. I note what it sounds like out of the box and check in on it weekly to see what if any changes have taken place. And I always have the ability to A/B it to my original equipment as well.
Some changes are significant some are not. For example I recently broke in an new amp which sounded harsh thru the upper mid's and highs. After 24 hours I put in some different tubes to smooth it out (I had a prejudice toward the original tubes as it were). A couple of months later I started experimenting with the tubes again because the amp had started sounding dullish. I put the original tubes back in - the harshness was gone, I'll be dammed. The difference was amp break-in over a long period of time, there was no other reason. Tubes or amp, take your pick!
I'm fairly objective, and certainly not dillusional. About the only thing I'm generally cynical about is lengthy PC, IC, and speaker cable breakin - much beyond 24-48 hours - but I will admit there is a lot of cable I haven't listened to and I'm not educated electronically speaking enuf to understand the basis for longer break in periods, if they exist.
However, FWIW, I would agree that at 100 hours about everything should have taken on a sonic signature that you can live with or not. 100hrs devided by 24hr + 4+ days. What's the big deal?
On a personal note, I recall when I could't even tell the difference between many speakers unless it was gross, let alone amps and pre-amps. We all have a learning curve and many folks on this forum are smack dab in the middle of it. IMHO.
