Designed to further optimize and elevate the exceptional CD performance. That dedication furthers the Marantz legacy of musical excellence with the SA-KI Ruby.
The legacy continues
HDAM technology combined with optimized circuit design layout and carefully selected components, it provides exceptional sound quality and performance.
Engineered and extensively tuned by a team drawing on more than 35 years of Marantz CD and SACD design knowledge.
Enjoy masterful playback from your SACD, CD collection and more the way you expect from a Marantz
Marantz innovative and proprietary SACD/CD mechanism “SACDM-3” designed purely for the best CD performance.
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.
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.
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.
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.
