About the MM6
The Darlington Labs MM-6 is a discrete solid-state phono preamplifier designed exclusively for Moving Magnet (MM) cartridges and high-output Moving Coil (MC) cartridges down to 1.6mV. It features a gain of +40dB at 1kHz, suitable for most MM cartridges, and uses a passive RIAA equalization scheme with precision components for accurate frequency response. The unit operates at 24 volts AC with an external power supply and is built in the USA with high-quality parts. It offers a frequency response of 20Hz to 20kHz within ±0.2dB, total harmonic distortion (THD) less than 0.08% at 1kHz, and a signal-to-noise ratio greater than 78dB A-weighted. The MM-6 includes an optional Iso-Pad for vibration isolation and supports custom input loading configurations. It is compact and lightweight, measuring 7" deep by 5 1/8" wide by 1 9/16" high and weighing 2.2 lbs. The MM-6 is often paired with the SU-6 step-up amplifier for lower output MC cartridges. It is praised for its neutral, musical, and transparent sound quality, making it competitive with phono preamps costing up to or more.
