About the Decade

The Lehmann Audio Decade is an advanced phono preamplifier designed to deliver exceptional sound quality for both moving magnet (MM) and moving coil (MC) cartridges. It features a two-box design: one chassis houses the PWX II low-noise power supply, and the other contains the audio circuitry including gain stages and RIAA equalization. The device offers four gain settings (36, 46, 56, and 66 dB) selectable via front panel switches with LED indicators, plus a soft bass rolloff filter at 50 Hz to protect speakers from excessive low-frequency energy. Input impedance options include 47 kohms, 1 kohm, 100 ohms, and a custom load slot for exotic cartridges. Input capacitance is adjustable between 47 pF and 1,370 pF. The discrete class A output stage provides an open, swift sound image capable of driving longer cables. The unit is highly configurable to accommodate a wide range of cartridges and user preferences, with ultra-precision passive RIAA equalization using low-loss MKP capacitors for accurate transient and dynamic reproduction. Dimensions for both audio and power supply sections are 110 mm x 280 mm x 50 mm, with the audio section weighing 0.87 kg. The Decade is praised for its spacious soundstage, fine dimensionality, and natural treble, making it suitable for demanding audiophiles seeking a musical and precise vinyl playback experience. It is
