Moon by Sim Audio 610LP Phono Preamplifier

Featuring a dual-mono, fully balanced differential circuit layout, the MOON 610LP is a purist design heavily based on the reference grade MOON 810LP.

Since one of our strengths at Simaudio is “Research & Development”, we have the ability to create a reference grade product and then, a short time later, offer a more accessible model which encapsulates most of the technology and performance of the reference.

The 610LP combines customized parts in an ultra-refined audio circuit which is fed by a unique power supply. This oversized power supply, located within the main chassis, is housed in a satin coated, steel isolated enclosure which eliminates all traces of AC artifacts. Located within this enclosure is a high quality toroidal transformer, a ‘pi-type’ filter to reduce AC transmission noise and multiple stages of voltage regulation. These factors result in a power supply that exceeds the performance of a battery power supply with respect to both audio signal-to-noise ratio and voltage regulation.

A highly configurable phono preamplifier, the MOON 610LP offers selectable gain, impedance loading, capacitance loading and equalization curves, all accomplished using DIP switches found 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 610LP to work with virtually any available phono cartridge.
