Featuring a dual-mono, fully balanced differential circuit layout, the MOON 610LP is a purist design heavily based on the reference grade MOON 810LP.
Key Features:
- 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;
- 64 impedance loading settings from 12.1Ω to 47kom;
- 16 capacitance loading settings from 0pF to 1120pF;
- 16 gain level settings from 40dB to 70dB;
- Selectable equalization curves for RIAA and IEC standards;
- Fully compatible with 820S external power supply;
- Customized parts include metallized polypropylene film capacitors with very tight tolerances of 1%.
Simaudio Ltd.’s Moon Evolution 610LP ($7500 USD) is an ambitious component: a fully balanced, feature-rich design. Its enclosure is milled from aluminum and, with dimensions of 18.75”W x 4”H x 16.8”D and a shipping weight of 40 pounds, it’s a chunky beast. Inside, the 610LP is most notable for accepting a balanced signal (as my Aqvox Phono 2 Ci phono stage has been doing for years), which is the optimal way to transfer the signal from a cartridge (the 610LP will also take a single-ended input). The signal that comes out of a cartridge is naturally balanced -- i.e., positive and negative, not positive and ground, as in a single-ended signal -- so it makes sense to take advantage of that fact. With most turntables, all you’ll need to use the 610LP’s balanced circuitry is a re-terminated cable.
The 610LP combines customized parts in an ultra-refined audio circuit which is fed by a unique power supply. Located within the main chassis, this oversized power supply is housed in a satin coated, 14-gauge steel isolated enclosure which eliminates all traces of AC artifacts. Also 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 supply with respect to both audio signal-to-noise ratio and voltage regulation.
A highly configurable phono preamplifier, the MOON 610LP offers selectable gain, 2 equalization curves, impedance and capacitance loading; 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.
