Preamplifiers are the the heart of any high-end music system controlling input selection, the critical first amplification stage, volume and balance functions, and the all important electrical isolation between sources and power amplifiers. Place the BHK Signature Preamplifier between your musical sources, and your power amplifier–and magic happens. Suddenly you are enveloped in a wealth of musicality you’ve not yet experienced: a deeper, wider soundstage, improved separation of instruments and voices, subterranean bass, extended highs, and an openness you have yet to experience without this instrument in your system.
The BHK Signature Preamplifier features two 12AU7 dual triode vacuum tubes in the input stage that act as a zero feedback balanced input amplification pair. A combination of an input stepped attenuator, built around the highest quality passive components for coarse volume adjustments, coupled with controlling the actual gain of the vacuum tube for finer steps, turned out to be the most sonically transparent level control we have yet heard. Finally, the output stage is a high-bias class A MOSFET design that is unaffected by cable and power amplifier interface challenges.
Preamplifiers play a critical role in any separates audio system, strategically positioned between sources of music: CD players, phono preamps, DACs, tape recorders and tuners—and your power amplifier—the preamp serves essential roles of control and isolation. The BHK Signature Preamplifier features 5 identical balanced and single ended inputs, and converts all input signals into a balanced signal for the lowest possible distortion, and can be used in a two-channel audio system or as part of a home theatre system. The high-bias Class A MOSFET output stage ensures unmatched performance with any cable and amplifier interface.
The BHK 250 stereo power amplifer is an industry reference standard for performance - a 250 watt per channel investment grade musical instrument that brings music to life.
The BHK Signature 250 Stereo 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 250/500 watts per channel. When cost-no-object performance is the goal there are a rare handful of power amplifiers capable of transporting listeners into a musical space few are able to enjoy.

If you are uncomfortable with compromise and seek the finest performance, reliability, and build quality in a single-chassis format, the BHK Signature 250 is a perfect fit.
Nothing in the design of a power amplifier is more important than its input stage when preserving music’s finest nuances. In the BHK Signature, a vacuum tube serves as the perfect interface between the preamplifier and MOSFET output stage. This hybrid approach offers stunning musical performance and unrivaled, effortless drive to the speaker. The Signature 250 Stereo Amplifier is the ultimate choice when a single chassis solution is required.
The BHK Signature 250 Stereo Amplifier produces 250 watts/ 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. Use this amplifier as the bedrock of your high-performance audio or home theater system. The BHK 250 provides the finest performance, reliability and build quality possible, in a single chassis format.
When you are unwilling to compromise performance, PS Audio offer the BHK300 Signature 300 watt Monoblock power amplifers. They are among a rare handful of amplifers capable of uncovering music's rich tapestry ina lush uncomprimised, effortless presentation.
The audio performance and build quality of the Signature 300 series has been refined, honed, and polished over the past half century of design work by industry legend, Bascom H. King. They are mono block amplifiers that produce 300 watts into 8Ω, 600 into 4Ω, and a whopping 1,000 watts into 2Ω. 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 that can drive any loudspeaker to musical perfection.
The hybrid vacuum tube/MOSFET design of the BHK Signature Amplifiers provides stunning musical performance through any loudspeaker.The Signature 300 Mono doubles the output current of the 250 Stereo, and doubles the tubes, power supplies, transistors, capacitors and resistors. The results are hard to put into words. Your first listen to these extraordinary monoblock amplifiers will likely be a revelation. For perhaps the first time you'll discover all that has been long buried in your musical collection. You'll know this amp was the right choice from the very first note you play.
The BHK Signature 300 Mono Amplifier is one of only a rare handful capable of uncovering music's rich tapestry in a lush, uncompromised, effortless presentation. If you haven't any barriers to perfection, the BHK 300s are perfect for any size system in the world, producing a minimum of 300 watts into 8Ω, a minimum 600 watts into 4Ω, and an astonishing 1000 watts into 2Ω. Enough linear amplifier power to bring life to music as you've only experienced with live music.
