Do speaker cables need a burn in period?

Oh yes, don't pay much attention to how they sound during this burning in period unless you want to have fun. Give them a time.

Yes. Heed the advice of everyone here. You'll notice the biggest changes in the first few days to a week and gradual changes thereafter but it will take time.

All the best,

My Audioquest speaker cables were purchased used, so i am guessing that they are already broken in. So far, all the responses are in agreement that they do need time to settle down, whereas from what I have read elsewhere there were more nays than yays. I thought I would ask a proper hi-fi community the question. Thanks for all your replies. 

Burn them in at 110db with analog source only !
Just kidding. But use various music. Don't assume that they were fully burnt-in. Do you know how many people, not audiophiles, sell their new equipment because in fact it was not properly burnt-in and naturally they didn't like the sound !

Inna, are you suggesting I play my music quietly? I compete with low flying aircraft when i play my 'digital' music haha, I do have turntables, one is orf elsewhere (LP12), the other is still its box and not seen the light of day (MF round table), and the final one actually set up is a, wait for it......, a Music Hall USB-1 (stop laughing) for all those Goodwill vinyl purchases, of which I have bought many. lol.........
