Cable Burn In


I'm new here and new to the audiophile world. I recently acquired what seems to be a really high end system that is about 15 years old. Love it. Starting to head down the audiophile rabbit hole I'm afraid.

But, I have to laugh (quietly) at some of what I'm learning and hearing about high fidelity.

The system has really nice cables throughout but I needed another set of RCA cables. I bit the bullet and bought what seems to be a good pair from World's Best Cables. I'm sure they're not the best you can get and don't look as beefy as the Transparent RCA cables that were also with this system. But, no sense bringing a nice system down to save $10 on a set of RCA cables, I guess.

Anyway, in a big white card on the front of the package there was this note: In big red letters "Attention!". Below that "Please Allow 175 hours of Burn-in Time for optimal performance."

I know I'm showing my ignorance but this struck me as funny. I could just see one audiophile showing off his new $15k system to another audiophile and saying "Well, I know it sounds like crap now but its just that my RCA cables aren't burned-in yet. Just come back in 7.29 days and it will sound awesome."

" N80 if you’re interested read up on confirmation bias and expectation bias. This is the reason for all the folks claiming that things sound wildly better when they’ve spent 1000s on a cable."

I'm actually very familiar with those things. I've dealt directly with clinical trials in my lifetime and assess the merits of them regularly. When dealing with humans subjective measurements are difficult and even more difficult to attach meaning to. The mind has a powerful effect not only on how we perceive reality but how we respond to it. The placebo effect, which is very relevant to this conversation, is a good example. In one study on placebo effect subjects who were extremely sensitive to poison oak were blindfolded and told poison oak leaves were being rubbed on their arm. It was actually an inert material. Despite this a certain percentage of the test group developed a rash where they were touched with the inert substance. No one in the control group did.

Anyway, I see exact parallels to these conversations in the photography world and in the automotive performance world.

Whenever I explore a new pursuit like this or photography or whatever, there is always a certain level of skepticism that any said expenditure for any said improvement is actually going to be real. I am often shocked how much actual, real improvement there is as you go from lower end gear (like lenses, camera sensors, etc) to the better equipment. You feel and know that the money spent has been worthwhile and it is easy to see and easy to prove. I firmly believe that this cost vs improvement curve goes up steeply for quite a while. But I also believe that at the higher end of the curve the performance curve begins to flatten out as expenditures continue to rise, usually more steeply. At this level the amount of money spent buys you very very little. I also believe that there comes a point that the performance goes completely flat even as expenditures go up. High cost, no yield.

I'm not correlating any thing in the audiophile world with any point on this curve. But it is always my goal to seek that sweet spot where the curve starts to flatten out, stop spending money and know that I'm getting the most out of my budget. That sweet spot is going to be in different places for different people.  But with significant experience in the photography world, I know there are folks who delight in that part of the curve where cost is high and the benefits are subtle at best. Nothing wrong with that as long as they don't try to convince me that the curve is still going up when it isn't. 

Of course the best thing to do in that situation is to thank them, shut up and walk away. I haven't got that down yet.
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.

I’ve noticed something, too, over the years. That is naysayers and skeptics tend to construct detailed, layered arguments to try to discredit or dismiss certain controversial ideas, products or tweaks. Cables is obviously just one example. And it’s the same ones who pop up on all of those threads. You could say it’s an excersise in the art of debate or the art of philosophical argument. But at the end of the day it’s simply what they choose to believe. I’m giving them credit here for honest debate, but even that is often in doubt. I’m not saying it’s not OK to have a gut reaction to something, but to build a whole philosophy around it? Hel-loo! I don’t think you’ll find any super skeptics suddenly changing their tune. Even with considerable evidence to the contrary from all sides. What would they say to the other super skeptics? I mean, come on!
Wind 'em up and watch 'em go!  If only a fraction of this energy was spent solving actual problems..

I've been experimenting with hifi for a few years. At first I felt the need to reject all the dubious ideas, like tweaks, fancy footers, cable burn-in, contact enhancers, etc. Then I pursued all these things avidly. My current feeling is that all of these things make a difference, but not so much really.
