Simaudio MOON 810LP Reference Balanced Phono Preamplifier

A true purist design that is destined to become the new reference for analog playback. Astonishing analog reproduction combined with unsurpassed flexibility!

A dual-mono fully balanced differential design, the MOON 810LP is an “all out assault” on phono preamplification. This is the result of a unique combination of customized parts in an ultra-refined audio circuit, mounted on a gel-based floating suspension and fed by a unique power supply. Its highly configurable nature - selectable gain (40 to 70dB), impedance loading (12.1 to 47k?), capacitance loading (0 to 1120pF) and equalization curves (RIAA & IEC) - 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 810LP to work with virtually any available phono cartridge.

“With the MOON 810LP, we envisioned a design with absolutely no restrictions; the ultimate goal being to transport all of the emotion from the artist in the recording studio to your living room.”

The oversized power supply, located within the main chassis, is housed in an isolated enclosure that is constructed from satin coated 14-gauge steel 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. Finally, on the actual audio circuit, there are 4 stages of M-LoVo - an all new proprietary MOON Low Voltage discrete DC regulation circuit. Combining all of these factors, the MOON 810LP’s power supply exceeds the performance of a battery supply with respect to both audio signal-to-noise ratio and voltage regulation.
