PS Audio Amplification

PS Audio BHK Signature Preamplifier

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.

DESIGN

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.

APPLICATION

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.

DESIGN

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.

APPLICATION

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.
