BHK 300 Monoblocks

About the BHK 300 Monoblocks

The PS Audio BHK Signature 300 Monoblocks are a pair of premium, hand-built mono power amplifiers designed by audio legend Bascom H. King in collaboration with PS Audio founder Paul McGowan and Arnie Nudell. These amplifiers are renowned for their hybrid circuit, combining a vacuum tube input stage (using matched pairs of Gold Lion 6922/6DJ8 tubes) with a high-bias, balanced MOSFET output stage, all assembled with through-hole components for reliability and serviceability. The design is fully balanced from input to output, with separate, isolated power supplies for the tube and solid-state sections. The BHK 300 delivers 300 watts into 8 ohms, 600 watts into 4 ohms, and over 1,000 watts into 2 ohms, making it capable of driving even the most demanding loudspeakers. The sound signature is characterized by exceptional imaging, depth, and a natural, uncolored soundstage, with a rich musical timbre and no loss of high-frequency detail. The amplifiers are large and heavy (83 lbs each), built to the highest standards in the USA, and are considered a reference in high-end audio for their combination of power, precision, and musicality.
