This "exceptionally powerful accessory" is a battery-powered travel alarm clock that has been "extensively modified using a number of highly-specialized techniques." How does this $199 precision instrument work? It probably doesn't. Read this: "While the clock can be placed anywhere in the listening room with good results, the best locations for the Clever Little Clock just might be near the boundaries of the building -- for example, on a window sill or shelf of an exterior wall. Remove the Clock from its clear bubble pack and place it anywhere in the listening room. The sound will be considerably more musical and live-sounding -- there will be less distortion, more information and a deeper, more coherent soundstage. Low frequencies will be articulate, extended and dynamic, high frequencies exceptionally smooth with phenomenal inner detail. In other words, More of Everything." www.machinadynamica.com/machina41.htm
