The PS Audio BHK Signature Pre-Amplifier offers an unrivalled performance, with no compromise in the construction or design. Uncover all the details of your music with the BHK Pre-Amp, with a wider soundstage, extended highs and deep bass.

The PS Audio BHK Signature Pre-Amplifier is the crucial link between your audio sources and the power amp, uncovering all the detail and dynamics in your music previously unheard. The BHK Signature uses a zero-loss vacuum tube input stage, fed from a discrete MOSFET high voltage regulator, powered by a high current oversized transformer. The large toroidal transformer analogue power supply feeds five MOSFET regulators, for clean, regulated power throughout the pre-amp.

The BHK Pre-amp uses fully balanced circuit topology, regardless of input type, either RCA or XLR. The fully balanced design ensures the lowest distortion and highest linearity. The pre-amp features discrete through-hole components, ensuring no compromise is made on the sound. The BHK Signature is meticulously designed and engineered by hi-fi industry legend Bascom H. King, with matching stereo or Monobloc power amplifiers, all with the same exacting standards.

With 5 balanced XLR inputs or 5 RCA stereo inputs, the BHK Pre-amp allows you to connect any audio source, including CD player, DAC, streamer or turntable, with fully balanced XLR or RCA outputs to a power amplifier. A built-in headphone amplifier allows you to listen privately, delivering a near perfect performance for any high-end headphones.
