Description

PS Audio BHK Signature Preamplifier

Preamplifiers are at the heart of any high-performance music system. They are the critical controlling interface between our sources of music and our loudspeaker chain. Most preamplifiers do a fine job of control and isolation, but only a rare handful make magic happen. Add the BHK Signature Preamplifier into your system and suddenly you are enveloped in a wealth of musicality you’ve not yet experienced: deeper, wider, sound staging, improved separation of instruments and voices, subterranean bass, extended highs, and an openness you’re unlikely to have experienced without this instrument in the 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.
