Do speaker cables need a burn in period?

From experience, cables require different amount of burn-in time.  Some of their materials require different times.  I've found that copper wiring takes much less time than silver wiring to burn-in.  Even my phono-cables took a lot time back in 1989 to settle in (maybe 100 hours) despite their small gauge.  My speaker cables took a long time but sounded great as soon as they were plugged in.  My ICs of all sorts take a minimum of 24 hours before I listen to them as their character changes significantly (I'm a cabling beta tester for a manufacturer so I know how raw a cable can sound brand new).

If someone gave you a 10 to 1, $ bet that you could pick out the the direction of your cables with a blind listening test, how much money would you risk?

Oh poor 23-post dude (or dudet), go back and read from the beginning.  Nobody can actually hear the difference in a “blind” or “double-blind” listening test.  But, that doesn’t mean there is no difference.  Many can hear a significant difference, just not under the confines of actual comparison tests.  Besides, a requirement to actually hear a difference would suck the fun out of keeping endless logs of listening notes after changing the direction of each and every fuse and cable one-by-one.

You should be able to hear the difference right off the bat. If not, send them back.

Not sure? Most of my cables have been purchased used.My speaker cables are new have about 10 hours on them so will I hear a difference in 100 to 300 hours on them I highly doubt it. Speakers yes cables I have my doubts the initial listening session is more than likely how they sound.I may have to eat my words in the future with my speaker cables but I doubt it.

The "difference" should be obvious, right off the bat. If not, send 'em back.
