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...
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?
