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.
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.
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.
