Pure Marantz Sound

HDAM technology combined with optimized circuit design layout and carefully selected components, it provides exceptional sound quality and performance.

Sound Master Tuned

Engineered and extensively tuned by a team drawing on more than 35 years of Marantz CD and SACD design knowledge.

Your Music Your Way

Enjoy masterful playback from your SACD, CD collection and more the way you expect from a Marantz

Asynchronous USB Input

Marantz innovative and proprietary SACD/CD mechanism “SACDM-3” designed purely for the best CD performance.

CDs, SACDs and Beyond

The SA-KI Ruby goes so much further than just disc playback: it's also a fully-functional digital-to-analog converter for music stored on a home computer, as well as having conventional digital inputs for existing source components. Those conventional inputs - optical and coaxial - can handle your music files up to 192kHz/24bit. Ruby to maintain signal purity and sound stability.

More Than a DAC

Built with an integrated DAC, the SA-KI Ruby features an all-new disc transport mechanism that re-engineers the digital to analog conversion. Taking full advantage of the 1-bit conversion technology, the SA-KI Ruby incorporates innovative new filtering and up-conversion, providing a simple yet elegant solution.

Marantz Musical Mastering: MMM-Stream and MMM-Conversion

At the heart of digital audio in the SA-KI Ruby lies DSD. PCM and DXD inputs are up-converted to DSD at 11.2MHz using the proprietary MMM-Stream converter within the player, and the high-frequency signal produced is processed by the unique MMM-Conversion stage, used in place of a conventional DAC, to produce the analog output.

High Current Power Supply

The power supply of the SA-KI Ruby features a large high current toroidal power transformer with OFC (oxygen-free copper) secondary wires, along with high speed, high current Schottky Barrier Diodes in the rectifier stage for the purest DC voltage output.

Built to Perform

Like the complementary PM-KI Ruby integrated amplifier, the SA-KI Ruby Super Audio CD player is constructed to the highest standards, with a copper-plated double layer chassis for rejection of mechanical interference, a front panel built from thick, heavy, non-magnetic aluminum panels and a 5mm thick aluminum top cover.
