PS Audio BHK Signature Preamplifier

The new PS Audio BHK Signature Preamplifier is the perfect interface between your sources and power amplifier. Designed by Bascom H. King, the BHK Signature distills Bascom’s 50 plus years of high-end audio design experience into a single masterpiece of audio amplification. “This is the best sounding preamplifier I have ever designed or heard,” and that’s saying a lot for a man of Bascom’s experience. 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. Control is simple in concept, but extraordinarily difficult to design in an acoustically transparent manner. Control duties such as input switching, volume, balance, and amplification can place unwanted acoustic thumbprints on the music if not designed with extraordinary care. The challenge in any design is to do as little damage to music’s purity as possible. What our Master Designer, BHK, has built will not only stand the test of time, but represents one of the finest musical instruments ever built to honour the music.

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 theater system. The high-bias Class A MOSFET output stage ensures unmatched performance with any cable and amplifier interface.

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.
