Denon AU-320 Step Up Transformer For MC Phono Moving Coil Cartridge

The Denon AU‑320 is a vintage moving-coil (MC) cartridge step-up transformer from the 1970s, designed to interface MC cartridges with standard moving-magnet (MM) phono stages. It offers selectable impedance settings of 3 Ω, 40 Ω, and a bypass mode, making it compatible with two turntables and various MC cartridge types. Housed in a rugged iron case with triple-layer shielding, it features gold-plated terminals and low-capacitance circuitry to minimise noise and signal loss. Praised for its exceptional bandwidth, low noise floor, and quiet operation, the AU‑320 remains a sought-after, purely passive solution for vinyl purists who want a clean, analog signal path without introducing distortion or noise.
