The Moon Simaudio 310LP (v1) phono preamplifier has fully adjustable MM and MC settings. MC gain has three options: 54, 60,and 66db through RCA outputs, with an additional 6db available through XLR outputs. Five impedance settings (10, 100, 470, 1K, and 47kΩ) are available for both MM and MC, meaning those with moving-iron cartridge can take advantage of the higher-gain settings. Capacitive loading can be set at 0, 100, and 470pf—a bonus for MM users, as it offers more flexibility. The 310LP offers a jumper setting for RIAA or IEC equalization. This level of functionality isn’t often seen at this price point.
The 310LP rear panel hosts single-ended RCA inputs and outputs, plus balanced XLR outputs. The 310LP is compact at just 7.5″ x 3.2″ x 11.2″, weighing 7 pounds.
This is a first generation model, and an ex-demonstration unit. Comes with all original packaging, but is outside of manufacturer warranty.
