The audio performance and build quality of the Signature 300 series has been refined, honed, and polished over the past half century of design work by industry legend, Bascom H. King. If there is a better performing power amplifier anywhere in the world, we are unaware of it. The BHK Signature 300 Monoblock designs are built upon two proven topologies: a zero-loss vacuum tube input stage coupled to a high bias differentially balanced MOSFET output. If you are uncomfortable with compromise and seek the finest performance, reliability, and build quality, the BHK Signature 300 series is a perfect fit.
