PS AUDIO BHK Signature 300 Mono Amplifiers - Black
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.
The BHK Signature 300 Mono power amplifier culminates one man’s lifelong quest for perfection in power amplification. Bascom H. King’s magnum opus combines a pair of vacuum tubes on its input with a double set of parallel MOSFET outputs capable of 300 watts in 8Ω, 600 into 4Ω and more than 1,000 watts into 2Ω. The BHK Signature 300 amplifier can drive any loudspeaker to musical perfection and is the most important element in your music reproduction chain.
