Burn In = Voodoo?


I have been an obsessive and enthusiastic audiophile for 20 years, I am not averse to tweaking and The Audio Critic infuriates me. However, I must admit I get a little uncomfortable reading so many posts about "burn in". While I understand that amps may need to warm up, speaker components may need to loosen up, the idea of burning in a cable or say, an SACD player just seems ludicrous to me. Unless of course, the party suggesting the burn in is a snake oil equipment peddlar and needs to make sure someone owns and uses your product for a couple of months before they decide it's really no good. At that point, of course, no one could actually remember what it sounded like in the first place and even if you wanted to return it, it would be too late. Am I being too cynical here?

Undo your burnt in speaker cables,curl them up,let them lie wherever for 24 hrs.Reinsert them; you should hear a difference in about 15/20 minutes.Same for power cords & ics.And no....don't stick them with a needle.
I beleive in pshcoacoustics, better power at night, and I think that livng with a piece is different from hearing it for the first time. I also beleive that over time you dont try as hard to hear a differece and relax allowing you to concentrate on the music. That alone allows it to sound better.

That said I had the oppertunity to compare two of the same model preamps. One was new and one was the display model. It was amazing how much better the broken in one sounded. I also think that my amps sound best after being on for a good thirty days. I absolutley hate turning them off.

I use to work with metal. Casting, rolling, and grinding. The characteristics of metal changes through certain processes like anneling or running current through it. I cant explain why but I know that it happens

I think that there a few who could explain it scientifaclly but the problem with the explanation is its hard to measure what ever changes the sound. I have a relative thats own a small computer company and we get in constant arguments on how one transport can sound different from another. He feels that digital is digital and there is no difference. We all know that isnt true and I think this situation fits into that catagory.

Most people with an electronics background dont learn about the effects of converting a signal to an analog soundwave. Not that there arent scientific reasons only that it is a highly unique and specialized feild. If you were to try to measure a difference you would need a meter that measuers and plots a sound wave. If it sounds different it must be shaped differently.
I can emphatically say that burn - in of a CD player is real. I just got a new player last month. The company includes a warning sticker on the player to let the player burn - in for 36 hours, before the player will sound its best. When I first hooked it up, I was disappointed. It was ever so SLIGHTLY better than my previous, long time player. And only in the area of detail. After over a month, I played both players next to each other(to try to hunt down a problem I was experiencing). The differences were now night AND day. It was startling, and brought a smile to my face. The new player was better in every area. Improving markedly in the areas of slam, dynamics, liquidity, and pace. Again, it was night and day. I have also experienced this with my current amplifier. Being disappointed and in panic initially, and feeling sublime about one month later(I also A/B'd that with my former amp). I am sure that people will feel that burn - in is just plain voodoo. But, I am one of the converted
We have had many posts on this subject, there no doubt is improvement in cables and components after several days of break-in, in my experience. Another factor which is hard to measure is your hearing adjusting to the different sound of the new item, as you become more used to it, sounds better etc.

Trelja, please reveal this new CDP you bought......
Magasam, I agree with you about the psychological effect of being infatuated with a component as time goes by, but only if it is a true improvement to the one we had before in its place. If its not "better", we tend to hate it, don't we, ever more deeply as time goes on until we get rid of it. Its sort of like adolescent love affairs. No wonder the other gender keeps telling us, that we never grow up. Thank the Audiogods, we don't!!
