More importantly, Bruce, I don't want to throw a big bucket of facts on the audiophillic fire here,
but "de-gaussing, polishing, trimming, etc" is HOOEY, JUNK "SCIENCE", P. T. BARNUMESQUE HOKUM!!!
This is why I can't take those "high end audio" magazines seriously -- they will sell advertising
and write articles about this junk!
