Marantz SA-KI Ruby CD Player
Signature Super Audio CD Player with DAC
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. Single layer, nickel-plated matching copper RCA terminals in the SA-KI Ruby outperform the terminals of competitors and offer an exemplary listening experience.
Marantz was in at the start of CD, launching its first player – the original CD-63 – in 1982. By then, Ken Ishiwata had been with the company for four years, and was to play a major role in the development of Marantz players from the start. But he went further than that: early on he realised that there was scope for highly-tuned versions of the company’s players, and thus was born the trend of Limited Edition, Special Edition and, latterly Ken Ishiwata Signature models, all designed to take the exceptional CD performance of Marantz models to the ultimate level.
Of these, perhaps the best-known is the classic CD63MkII KI-Signature, which Ishiwata describes as ‘still one of the most musical CD players we’ve produced.’ Now there’s a new classic, engineered and extensively tuned to mark Ishiwata’s 40th anniversary with Marantz – the SA-KI Ruby. Drawing on the development process for the flagship SA-10, and designed by the same team, the SA-KI Ruby features a new disc mechanism built purely for audio, the “SACDM-3”, able to play SACDs, CDs, and compilations on CD-ROM or DVD-ROM. It also has an asynchronous USB input, able to handle formats all the way up to PCM / DXD 384kHz/32bit and DSD11.2MHz, and handles all digital music with a unique Marantz Musical Mastering technology
By upconverting all file formats to DSD, using advanced filtering and processing, then using employing direct 1-bit conversion to feed the analogue outputs, the SA-KI Ruby delivers a sound with vivid detail, effortless dynamics and remarkable presence – all qualities central to Marantz CD players over many generations.
The Marantz engineering team has created this player not just to mark Ishiwata’s 40th anniversary, but also to deliver the kind of sound able to bring you closer than ever to your favourite music. The reason is simple, and central to everything Marantz does – “Because music matters”.
