For more than 4 decades, our vacuum tube preamplifiers have set the industry standard for performance, garnering worldwide acclaim and a place in many a reference system.


Since our first amplifier, the MV75 of 1978, c-j vacuum tube and solid state amplifiers have defined the state of the art. Our line features power amplifiers to fit nearly any requirement.
