The AMP-13R challenges the perception that the bigger the amplifier, the better the sound. Designed for audiophiles who value minimalism, it is the smallest possible, high-end analog audio amplifier that is not just another “square box”. The floating illusion of the slim case is achieved by the hidden heatsink footers, and the tallest component, the power transformer, is seamlessly built into one of footers. The entire function is controlled by just a single red Urushi lacquered knob, and 10 LEDs ingeniously display all 50 steps of the volume, offering a hypnotic focal point for this unique and efficient design.
