Ask yourself this question -- after the "burn in" what physically has changed in that cable?

Geoff, what time do you get UP in the Morning. You post was at 5:01 AM Eastern time???I guess the early bird gets the worm....The change after burn in, the insulation has a charge.
As for cryo and how can you tell? Trust in the person who did it. Plus the problem of what degree Kelvin and how long kept there? Some cryo treatments are way better than others.

I have some very pertinent experience with this issue. My long-time balanced interconnects (Clear Day) on the link between my Oppo/ModWright 105 CD/SACD player and Aesthetix Calypso linestage have served me well without complaint over the last 3-4 years. Great cables.
Recently a bat-eared audiobuddy suggested I try Duelund 20g ICs, also balanced, and since they were reasonably priced ($175), I figured, why not. When first inserted in my system they were awful -- flat, closed-in, meh in every respect. Again, the prescribed break-in (200 hours) sounded incredible to me. Fortunately I have an Audiodharma Cable Cooker to speed the break-in process.
So I gave the Duelunds several days on the cooker and compared them again to the Clear Days. Better, but no cigar. It took more days (I lost count), but eventually the Duelunds won the sonic battle and have now replaced the Clear Days. Note that there was absolutely nothing wrong with the Clear Days and a number of other ICs haven’t come close to the way THEY sound. But the Duelunds are now top dog -- sweet.open, clear, musical --and I haven’t an objective clue as to why. Not really.
One thing sure: The Audiodharma Cable Cooker is an incredible product, as anyone who owns one will likely attest Actual listening and comparing experience.... Who da thunk!..... And at the end of the day you clearly can hear the difference between the Clear Days and Duelunds. Jim |

FWIW, over the years I’ve noticed a fairly consistent phenomenon in these forums. Certain members seem to gravitate to threads involving phenomena that are either technically inexplicable, at least when considered in a quantitative manner (if that is even possible), or are particularly controversial, or both.
The usual result being that potentially constructive dialogue gives way to some combination of childish commentary, exchanges of insults, and ad hominem attacks, rather than dialogue which is constructive and potentially useful. Which as far as I am concerned would seem to defeat the main purpose of a forum.
Just an observation, FWIW. Also, BTW, I consider contributions to this forum by Prof and by Analogluvr, among a number of others I could name, to be the antithesis of those I am referring to. I always find their contributions to be pragmatic, thought-provoking, based on extensive experience in many cases, and certainly warranting intelligent discussion.
Also, as usual Jim (Jea48) has provided a constructive input to the thread. The problem, though, is that all too often audiophiles tend not to perform their evaluations in as thorough and disciplined a manner as he suggested, before proclaiming that a perceived difference is attributable to a specific cause. As opposed to being caused by extraneous variables such as ongoing aging or breakin of unrelated system components, differences in AC line voltage or noise characteristics that occur from time to time, changes in ambient temperature and/or humidity (temperature being a factor that is fundamental to the physics of semiconductors such as transistors, diodes, and integrated circuits), differences in equipment warmup states, flushing of internal digital memory that occurs when power is cycled, etc.
My own belief, again FWIW, is that when it comes to controversial audio-related matters more often than not reported perceptions are likely to be accurate, and not the result of "expectation bias." Depending, of course, on the credibility of the particular person who is doing the reporting. But my belief is also that in many cases the methodology that has been used in arriving at the reported conclusions has not been sufficiently thorough to assure that the perceived effect is being attributed to the correct variable.

One day to the next. Early morning, middle of the day, evening, or late at night. Though in the case of an A/B listening test between 2 cables the odds of any of the things you mentioned would be a factor is slim at best. The time, conditions, should, will be, the same for the short time intervals listening for the differences between the 2 cables to the trained ear. Again listening for differences...... For what sounds best at the end of the day dopogue post hits the nail on the head. What he hears is all that matters. Jim |
I believe it is a matter of degree. For sure new speakers and certain crossover capacitators benefit from long term burn-in. Speaker cables vary quite a bit since you have enormous power, current and phase considerations so burn in there is rational.
I find that balanced line level (XLR) cables are the least variable interconnects while unbalanced low level cables (phono cables) display more differences. With that in mind then it makes some sense that break-in of sensitive components: Tubes, Capacitators, Speakers and, to a lesser extent, solid state devices, switches and even some kinds of wire is rational. The differences are, however, variable.
