“Form follows Function,” the maxim of Louis Henri Sullivan, and “Less is More” by Ludwig Mies van der Rohe shape our ideas of good circuit and device design. These guiding principles from modern architecture can readily be applied to all areas of technical design. Almost surprisingly, products designed according to these rules not only fulfill their intended function exceptionally well but also satisfy the highest aesthetic demands. It is therefore only logical that devices surrounding us in everyday life - whose purpose is to engage us on a positive emotional level - adhere to these design principles. A good audio system should appeal to all the senses - not just the ears, but also the eyes and the hands.
