A dual-mono fully balanced differential design, the MOON 810LP is their first Evolution Series phono preamplifier. Representing an "all out assault" on phono preamplification resulting from a combination of customized parts in an ultra-refined audio circuit which is mounted on a floating suspension and fed by a unique power supply. Its highly configurable nature - selectable gain, impedance loading, capacitance loading and equalization curves - is accomplished using DIP switches located on the bottom panel. These switches are located directly in line with the circuit at optimal locations to yield the shortest possible signal path. These adjustments, in conjunction with an excellent overload margin, allow the MOON 810LP to work with virtually any available phono cartridge. 

The oversized power supply, is housed in an isolated steel enclosure to eliminate all traces of AC artifacts. Within this enclosure is a high quality toroidal transformer, a "pi-type" filter to reduce AC transmission noise and multiple stages of voltage regulation. On the actual audio circuit, there are 4 stages of M-LoVo (MOON low voltage DC regulation circuit).

Available in Black, Silver, or Two-tone.
