"For many years Simaudio has had a strong desire to offer the very finest phono preamplifier, based on available technologies. We envisioned a design with absolutely no restrictions; the ultimate goal being to transport all of the emotion from the artist, sound engineer and producer in the recording studio to your living room. With the MOON 810LP we have accomplished this and much more. Listen and feel for yourself how the power, the emotion and the soul of the music will reach you in ways like never before." Jean Poulin, CEO Simaudio Ltd
A dual-mono fully balanced differential design, the MOON 810LP is our 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 810LP to work with virtually any available phono cartridge.
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 DC regulation circuit. Combining all of these factors, the MOON 810LP’s power supply exceeds the performance of a battery power supply with respect to both audio signal-to-noise ratio and voltage regulation.
-
Power supply voltage regulation includes i 2 DCf (Independent Inductive DC Filtering); 1 inductor for each and every IC in the audio circuit’s signal path – 24 stages in all.
-
The dedicated audio circuit board is mounted on a 5-point gel-based floating suspension, derived from our M-Octave technology, originally developed for our reference 850P Preamplifier.
