Peter,
I think Doug found that with the Talisman repeat demags are necessary, and maybe Walker advertises it as so. So far, with the stronger magnet, I have not found it necessary to repeat the demag on any LPs.
I do also pull my tubes and cables every 6 months or so to clean and demag them. That actually may be too long of a time between demags of the cables. I haven't really experimented with it.
