PS Audio announced the PerfectWave BHK 600 Mono Power Amplifier, something they are dubbing “the finest amplifier ever created” by the company. The BHK 600 is the last audio component to be created with the collaboration of engineer Bascom H. King, and is PS Audio’s new flagship amplifier.

The PerfectWave BHK 600 delivers 600 watts of power into 8 ohms (1,500 watts into 4 ohms). PS Audio says it is fully balanced in operation from input to output, and can also be used in single-ended mode, offering a choice of balanced XLR or single-ended RCA inputs. It features an input stage with two hand-selected vacuum tubes, operating in conjunction with a rectifier tube and an exclusive N-channel MOSFET output stage. The tube rectifier was chosen rather than a solid-state device because of its improved sonic characteristics that result from the reduction of switch-mode noise common to solid-state rectifiers.

The BHK 600 features a separate output-stage power transformer with a massive 1.6kVA capability – more than twice that of the PS Audio M300 mono amplifier – enabling the BHK 600 to drive even the most inefficient loudspeakers and difficult loads with ease. The power supply has more than 300,000µf capacitance and multiple N-channel MOSFET output devices for a high damping factor of greater than 100. The BHK 600 has two pairs of heavy-duty gold-plated copper binding posts, to facilitate speaker bi-wiring.

The BHK 600 is available in silver or black.

The PS Audio PerfectWave BHK 600 Mono Power Amplifier will be available in late September 2022 at a price of $32,498 per pair.
