I run each roll of silver hook-up wire on the line side of a 100w light bulb for a day to precondition it....Been doing this for about a decade and it works fine to loosen things up, but don't go for more than a day....
12 Volt Cable Burn In?
I just made a pair of CAT 5 speaker cables following the Venhaus recommendations. A gentleman who worked at the cable vendor suggested that a speedy break in could be accomplished by connecting one cable end to a light bulb receptacle and the other to an electrical outlet and illuminating a 12 volt bulb for 24 hours. Any thoughts?
