Product Description

PS Audio BHK 300 signature mono power amplifier is built in the finest quality, refined and polished to meet gold standards of power amplification. It features a low-loss vacuum tube input stage coupled to balanced MOSFET output.

Musical Perfection

The BHK Signature 300 Mono power amplifiers can drive any loudspeaker with ease. It delivers 300 watts in 8 Ohms, 600 into 4 Ohms and more than 1,000 watts into 2 Ohms for massive power and performance. Designed and refined to perfection means the Signature 300 performs to unsurpassed standards, ensuring stunning musicality without compromise. 

Zero-Loss Input

Critical to the performance is an input stage that preserves all the musical details. When connecting the pre-amp and power amp, a lot of details can be easily lost. The vacuum tubes used in the BHK feature far greater quantities of electrons which ensures subtle and powerful musical information are passed without loss. The vacuum tube and MOSFET design with low feedback and wide bandwidth assure your loudspeaker reveals the tiniest details in music, clearer than ever.

MOSFET Output

The hybrid design of the BHK Signature ensures the best technologies are combined from both MOSFET's and vacuum tubes, which is highly beneficial. The MOSFET section can handle power without the need for additional circuitry like tube power amps require. They also sound a lot better. N-Type MOSFET's used in the amplifier produce almost perfectly balance waveform and much lower distortion than P-types.

Built By Bascom

Industry legend Bascom H.King took the lead in the design of the BHK Signature 300. Re-imagining the amplifier as a hybrid tube design led to the creation of this amplifier with vacuum tube input and MOSFET output stage. The output is regulated to preserve musical details and ensure low noise. A pure, clean  path is achieved by implementing high quality hand selected passive components. Even the connectors are crafted using copper gold plated for a quality connection. The BHK Signature 300 truly showcases the passion and craft of one man.
