Audio Products

Audio amplifiers are our specialty. All our designs employ  patented power MOSFET output stages, as they have proven to us the greatest potential for exceptional musicality and satisfying subjective and technical performance. Our goal, in a nutshell, has always been to create designs and implementations that performed in the realm of the multi-thousand dollar esoteric equipment, and make them available as kits to create an exceptional value and a highly satisfying experience.
