To my mind, applying what a person learns, to make a superior product, is what any Craft is all about. I see there is still continuing envy, regarding Greg Roberts taking Hi-end audio by storm. I for one, find his products to be outstanding, as do many of the people who used to dislike Horn loudspeakers. I still assert that PWK would be tickled by what Greg is doing. I am willing to bet, that PWK would have liked to be able to afford to this, and build this type of loudspeaker, using the truly best components available, and be able to make a profit, as Greg is.
