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?

Jim's post is FAR too sensible to be listed in this forum : ) Most of the stuff that he listed ( CD "stabilizing rings", markering the edges, etc...) all DETRACT from disc readability. The only thing that i've found to make a noticeable improvement to CD's is the Audio Desk Systeme "Disc Cutter". If i didn't hear the difference, i surely wouldn't have spent several hundred dollars on it. As to comments about "burn in" of electronics, that is measurable and called "settling" of the components. Capacitors need to "form" and this is a gradual process. If they are not used for a long time, the process starts all over. This "might" be true of wires and their dielectric materials also, but i don't know for sure. Most of what i've read about "wires" is that there is a crystal structure that is damaged or "stressed" when it is disturbed via movement or bending. Since i just picked up a "Mobie" cable burner ( already had a Duo-Tech ), i will be checking into this in the very near future. Several folks that i know and trust INSIST that using one of these does make a beneficial difference to the performance of cables. Either way, i'll soon find out if "I" notice the difference that it makes. Sean

Jeeez guys, let's take it easy. A cable conducts suitably or does not. Period. According to the French power corp, differences in sound are due to losses along the length of the conductor. Losses ARE affected by micro-movement (=vibration), i.e., in audio, the losses appear on variable points across the spectrum. This includes components (that are also conductors, right?). Hence, spikes, et alia. But don't set yr house on fire trying to burn-in cables... just hook them up and wait a bit while the system gets rolling...

Sean, I like your post, simply because I can underwrite every point you make. Incidentally, I also have this nifty German machine, which indeed DOES nake a difference.(Careful though, because Jostler rightly pointed out my autosuggestibility (; Would not miss it anymore, inspite of all the messy plastic threads having to be gotten rid of. If anybody is interested in the US outlet for this thing, mail me.

Hi Sean & Detlof... would you please give us more info regarding "disc cutters". Thanks, Jim.

Jim, call Cable Co about Audio Desk CD edge bevel machine.
They sell a special package of Audio Desk and Furutech RD-1 demagnitizer at reduced package price. If you buy duplicate
CDs you can send one to them and they will bevel & demag one
for you to compare. This is a fairly expensive tweak.

A word of caution, I will not use this even if it "seems" to
work now because it violates my golden rule about CD Tweaks:
NEVER APPLY A TWEAK THAT CAN'T BE REMOVED! Here is link to
Cable Co special for Audio Desk: www.fatwyre.com/newspecials.html
