PS Audio BHK Signature 300 Mono Amplifier pair (Silver)


Power amplifiers are the make-or-break component in the music reproduction chain. Everything in your system funnels into this critical component; anything lost can never be recovered. The BHK Signature features a zero-loss vacuum tube input stage coupled to a high bias differentially balanced MOSFET output. This amplifier has few rivals at any price and, in terms of sheer musicality, openness, tonal richness and accuracy, none.

The BHK Signature power amplifier culminates one man’s lifelong quest for perfection in power amplification. Bascom H. King’s magnum opus combines a vacuum tube input with a powerful MOSFET output capable of either 300/600 watts per channel in the Mono 300. The BHK Signature Series amplifiers can drive any loudspeaker to musical perfection and is the second most important element in your music reproduction chain behind the loudspeaker itself.
