Either/both : ) Just trying to get a feel for this "quiet" company, and the person. SOUND APPLICATION has had some very complimentary reviews-but I haven't seen any from TAS or Stereophile. I'm curious. It does seem his products are very pragmatic; as well as "green" - ie no fluff, gloss or 'added weight'-to show 'value'. Also truly "Audiophile" with impeccable build quality and fanatical attention to materials selection and design.
