Harvey Rosenberg vs Ralph

You may recall years ago that Ralph had shall we say a disagreement with Harvey Rosenberg. Harvey tested an M60 and then insisted on installing inductors in the output stage power supplies. (I cannot recall whether he converted the supplies to inductor-input or just added inductors to create a CLC filter.) He then claimed he had made a major improvement in the sound. Ralph argued that adding inductors with considerable DCR was a no-no. No one gave in, but I think Ralph was correct in light of Broskie's dissection.
