The following has been suggested, what do you think...
Break in for cables makes a difference. Are we really burning in the cable or settling the dielectric ? Both actually. The conductor takes minimal time of constant play to burn in a path of least resistance. It is the dielectric that needs to form. Constant play for many hours of break in does not allow the dielectric to cool down to form.
A method of 24 hours on (continuous playing) then 6 hours off then 6 hours on then 6hrs off and so on until cooking/burnin is complete...
