Thanks for speaking up, Paul. I believe that electrons move at the same speed in most kinds of devices… :-)

I'm sorry, but the idea that "euphonic distortion" is an inherent characteristic of tube circuits is one that's been carefully nurtured by the purveyors of tube hi-fi gear. I'll go on record as saying categorically that it ain't necessarily so.
