The MOON 820S is the large and eagerly anticipated power supply that offers an upgrade path for certain Evolution series models.
Everything Simaudio knows about power supply design with respect to circuit layout, filtration and regulation has gone into the making of 820S. Designed to elevate the performance of products that already perform stratospherically at their price points, the 820S was created through painstaking R&D, creative ingenuity and a passion for perfection.
Featuring state-of-the-art, custom-built dual toroidal transformers, choke filtering and Simaudio’s own MOON Reference Regulation System (M-R2S) circuit, the 820S is capable of doing what was once thought of as virtually impossible: improving on the already superlative power supplies built into our products by further reducing the noise floor while maintaining an even greater voltage stability. The astonishing sheer “blackness” of the musical background created by the addition of this power supply must be heard to be believed.
The 820S is equipped with two sets of outputs. It can upgrade the performance of any one, or any combination of two of the following MOON products simultaneously:
- 740P Preamplifier
- 650D, 750D DAC/transports
- 780D DAC
- 610LP and 810LP phono preamplifiers
Each output provides DC power for both analogue circuitry (audio) and digital circuitry (controller, CD transport, front panel displays) on 2 separate and unique XLR type cables.
