ℹ Product Information
This PS Audio BHK Signature Preamplifier is an Ex Display unit, there is one available in black.
Preamplifiers are 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, such as a phono preamp, DAC, tuner or auxiliary source–and your power amplifier–and magic happens. 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 have yet to experience without this instrument in the system.
