PS Audio BHK Signature 300 Monoblock Amplifier (each)


I spent a few months thoroughly enjoying them without reservation—especially their engaging transparency, transient delicacy, harmonic and textural richness, and convincing timbral accuracy.


The BHK Signature 300 should be an outstanding performer in virtually any system I can think of, with the possible exception of extremely efficient horn systems with limited tolerance for power. These amps are truly powerful.



The BHK Signature 250 and 300 power amplifiers are the culmination of one man’s half-century search for perfection in music’s reproduction. Bascom H. King has designed amplifiers for many companies, some selling in excess of $100,000, including Constellation Audio, Marantz, Infinity, and Conrad Johnson. This is the first amplifier Bascom felt was good enough to lend his name to. It is his finest achievement in a lifetime of work.

Available in both stereo and mono models, the BHK Signature series is unparalleled in its ability to render details formerly lost in the music. The BHK Signature is a hybrid design enjoying performance benefits from multiple design techniques including, a balanced differential vacuum tube input, balanced differential MOSFET power outputs, and separate, isolated, analog power supplies feeding each.

When it comes to musically controlling and powering loudspeakers, the BHK Signature has no peer. The stereo Signature 250 produces 250 watts/per channel into an eight-Ohm loudspeaker, 500 watts/channel into four-Ohms, and stable into 2-Ohms; enough power to satisfy even the hungriest of loads.
