The Motherlode II

Elevate your audio setup with our meticulously crafted preamplifier, designed for audiophiles seeking unparalleled sound quality.

Product Description

Unmatched Craftsmanship and Sound Quality

The Motherlode II is my flagship line-stage preamplifier! It delivers an organic yet extremely fast and transparent rendition of the audio signal using boutique parts throughout. This model can use both 6SN7s and 6SL7s. This product will now feature Jupiter copper foil coupling caps.

The Motherlode II features a two-chassis design with a separate power supply and “twist-lock” umbilicals. The power supply employs a split toroidal power transformer, Hybrid bridge rectifier, all film capacitor filtering, three chokes (the latter provide additional channel isolation), Vishay wire-wound resistors, and a 5U4G rectifier and (2) OD3 regulators and copper shielding housed in a Purpleheart chassis with Maple and Walnut accents. The preamplifier uses paralleled Vishay resistors throughout the tube signal path, Mogami internal wiring, a Khozmo remote volume controller, Miflex PIO coupling capacitors, tube isolation damper plates, a resistor-based output level control, and Neutrik connectors in the same Purpleheart chassis.
