Fein

About the Fein

The Brinkmann Fein phono preamplifier has been in production since 1985 and is renowned for its refined sound quality and robust engineering. It features a single input with a volume control and low output impedance (200 Ohm), enabling it to drive power amplifier inputs directly. The Fein operates in pure Class-A with all operating points referenced to a single, temperature-compensated voltage source. Its power transformer avoids magnetic saturation through the use of ultrafast diodes and noninductive resistors. Due to its low power consumption, the Fein is designed to remain powered continuously for optimal sound quality. It includes a granite base for isolation and comes with an external power supply. The device supports switchable input sensitivities for MM and MC cartridges, with input impedances tailored for each type. The phono stage has a frequency response from 20 Hz to 50 kHz, very low distortion (THD/IM 0.01%/0.05%), and a signal-to-noise ratio of 80 dBA for MM and 78 dBA for MC. Dimensions are 120 x 80 x 160 mm (with granite base), and it weighs 1.5 kg (granite base 2.8 kg, power supply 1.2 kg). It is considered a classic yet continually refined product in the high-end audio market, though it is discontinued as of 2025.
