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.
