The BHK Signature PreAmp has a hybrid circuit with an input stage on low-signal 12AU7 lamps without OOS and an output stage on MOSFET field-effect transistors. The quiescent current of the lamps adjusts automatically, so that, if desired, the user can try other types of dual triodes.

More components

  • Stellar Phono Preamplifier

    Preamplifiers

    PS Audio Stellar Phono Preamplifier

    The Stellar Phono Preamplifier has two inputs that support the pickup heads (cartridges) both with a movable coil (MS) and a movable magnet (MM), or a turntable with two tonearms, allowing you to choose the best option at the discretion of the user.

  • StellarGold Preamplifier

    Preamplifiers

    PS Audio StellarGold Preamplifier

    The Stellar Gold preamp is equipped with two discrete element amplification stages, both of which have extremely high signal rise rates, wide bandwidth, and can process audio with negligible distortion. Based on a combination of field-effect JFET and bipolar BJT transistors, along with carefully hand-selected components, this preamplifier carefully transmits the musical signal without interference from the capacitors in the signal path.

  • PMG Signature Preamplifier

    Preamplifiers

    PS Audio PMG Signature Preamplifier

    PS Audio's PMG Signature Preamplifier is the company's flagship, the first product in 50 years named after the brand's founder. The device provides a high level of clarity and sound control, and has a dynamic range approaching 150 dB.
