The Amp 5.3 is a fully featured, high current mono power amplifier. With high quality components housed within heavy-gauge steel, these amplifiers sound as impressive as they look. Fan cooled, all-discreet output devices stay cool while driving even the most demanding speakers. Large toroidal power supplies and oversized capacitors ensure sufficient headroom while staying stable into loads as low as two ohms. And despite their modular design, they can also be used as powerful individual amps.
