The MOON 320S dedicated external power supply brings the 310LP phono preamplifier to a level of performance that is unmatched at this price and miles ahead of the competition. Reference level analog playback just became even more accessible.

Housed in a chassis identical to the 310LP, the 320S features a special "pi-type" filter and a dual voltage regulation system that reduces the 310LP's already very low noise level on the DC signal by a mind-numbing 150dB. 

Some of the benefits that the MOON 320S brings to the 310LP's already astonishing sonics are an even better signal-to-noise ratio that leaves you with the impression of increased gain; more realistic rhythm and pace; the increased presence of intricate details within the music; more natural life-like high-frequencies that allow you to better differentiate between various cymbals in a recording, and a deeper blacker background.
