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.
