Burn in period


Why would a copper speaker cable or rca interconnect need a burn in period.?  Are they really directional?

@lordmelton - I'm pretty sure speakers (drivers) are powered by ac current.  It's my understanding that the plus from your amp provides an AC signal to the speakers.  The signal travels through the speakers back to the minus terminal, which is ground.  Electrically, it would probably be more accurate to call these terminals hot (or +/-) and neutral.  However, if I understand how transformers and capacitors work, audio signal can only be AC and goes from positive to negative; hence, the flow (current) switches direction.    

Love the comments! Hilarious. I am not sure about cables having to “break in” to sound their best. It could be simply that it’s our ears & mind getting accustomed to the new sound?? No doubt cables of all types in a system sound differently from brand to brand & model to model & of course the law of “diminishing returns” applies greatly to this. 
 

For those of you who think cables don’t need to “break in” to sound their best, explain why most amps sound much better after they’re warmed up for an hour or two? I’ll bet they would measure the same from the moment you turn them on. Rogers tub integrated amp is a very well made, high quality product & I’ve noticed even after it’s warmed up that the sound changes when it’s playing for  a few songs.  That said, I’m also using new speaker wire….. life’s mysteries…..

Burn in is largely bull. Purely preached  by marketers to leverage your unconscious bias.
