The PM-KI Ruby is built with just one aim – audio performance – which is why it uses a fully discrete two-stage design with separate power supplies for the preamplifier and power amp section to reduce interference, and draws on the design of the flagship PM-10 amplifier with its moving coil/moving magnet phono stage and Marantz HDAM technology throughout for signal purity.

The KI Way.
Few hi-fi companies, if any, can say that one person has steered their sound for four decades – like Ken Ishiwata does at Marantz. The KI Ruby SACD player and amplifier go beyond even the standards of past KI Signature achievements, embodying all of Ken Ishiwata’s experience and expertise. Therefor they carry Ken Ishiwata’s signature as integral part of their design.
The Early Years.
Ken Ishiwata has been at the heart of Marantz for 40 years, but his influence extends beyond the many wonderful products he has developed for the company in that time.
A Special Way of Listening.
He has a unique ability to conceptualise stunning sound reproduction, design the equipment required to achieve it, and then deliver enthralling demonstrations around the world leaving listeners spellbound with the new insights Marantz products can deliver into even the most familiar music.
Refining the Harmony.
In exploring every aspect of every design, just occasionally he finds a product with extra potential, which he can then take beyond the Marantz standard and into something even more special. A KI Signature product is born.
Bringing Listeners Closer to Music.
The knowledge of how to make a fine-sounding product truly magical has grown with each new KI Signature launch – by improving sound-critical components through a process of careful selection and subtle blending, testing, listening and testing again.
Marantz SA-KI Ruby Ken Ishiwata Signature Super Audio CD Player with DAC
Marantz has been designing and making amplifiers for more than 65 years, and for 40 of those the products have reflected expertise of Ken Ishiwata. Now, to mark his four decades with the company, the SA-KI Ruby SACD player has been developed and tuned by a highly experienced engineering team led by KI himself. Features the same disc mechanisms as the SA10 that play SACDs, CDs and compilations on CD-ROM or DVD-ROM. The SA-KI Ruby includes an asynchronous USB input that handles formats up to PCM/DXD 384kHz/32bit and DSD11.2MHz and treats all digital music with a unique Marantz Musical Mastering technology. By up-converting all file formats to DSD, using advanced filtering and processing and direct 1-bit conversion to feed the analog outputs, the SA-KI Ruby delivers sound with remarkable clarity, effortless dynamics and exceptional presence—plus, features a laser-engraved Ken Ishiwata signature to commemorate his legacy.
Celebrating 40 Years of Passion
Designed to celebrate the 40-year anniversary of legendary Marantz sound master, Ken Ishiwata, SA-KI Ruby features pinnacle performance that’s synonymous with Marantz excellence. Complete with thoughtful engineering, painstaking tuning and extensive listening sessions, SA-KI Ruby achieves the elevated output worthy of its name. Elegantly features Ishiwata’s laser-engraved signature to commemorate the design and heightened listening experience that honors the decades-long partnership between him and Marantz.
A History of Excellence
A pioneer of CD playback and musical integrity, the first Marantz CD player — the CD-63 — premiered in 1982 and set the stage for further development and mastery of CD media players. Ken Ishiwata helped sculpt Marantz media players into the world-class, masterful technology that is synonymous with Marantz today. From his passion, the Limited Edition, Special Edition and later Ken Ishiwata Signature models were born — all designed to further optimize and elevate the exceptional CD performance of Marantz media players. That passion furthers the Marantz legacy of musical excellence with the SA-KI Ruby.
At the heart of the SA-KI Ruby is an innovative new SACDM-3 transport mechanism, engineered solely for the best possible performance when playing SA-CDs, CDs and music stored on data discs. This new mechanism promises exceptional sound quality from conventional CD and SA-CD discs and allows listeners to create their own high-resolution audio compilation discs using a computer DVD burner. The SA-KI Ruby supports FLAC files from 44.1kHz to 192kHz at up to 24-bit resolution, DSD2.8MHz and DSD 5.6MHz, ALAC (Apple Lossless), AIFF and MP3 files. Creating and playing hi-res disc compilations is as simple as it is enjoyable.
CDs, SA-CDs and Beyond
The SA-KI Ruby is a fully functional digital-to-analog converter for music stored on a home computer and features Optical and Coaxial digital inputs for existing source components. These inputs support files up to 192kHz/24bit and contain a USB-B asynchronous input for direct connection with a computer. The USB-B input is compatible with PCM and DXD music files at up to 384kHz/32bit, as well as DSD2.8MHz, DSD5.6MHz and DSD11.2MHz.
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. The MMM-Stream section of the process replaces the oversampling filters normally used in digital to analog conversion and allows the implementation of the Marantz Musical Mastering filtering. Two system clocks ensure the most accurate up-conversion of the incoming signal, whether it’s from the disc or digital inputs, ranging from 44.1kHz to 12.288MHz. Sigma Delta Modulation allows a pure DSD-standard signal to be passed to the conversion section in the form of a very high-frequency stream of pulses. The design of the DSD-to-analog filter feeds into the familiar Marantz HDAM (Hyper Dynamic Amplifier Modules) in the output stage for optimal sound quality.
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.
System Remote Control
The elegant remote control features an intuitive ergonomic layout and is equipped with amplifier control functions to operate both the SA-KI Ruby and the complementary PM-KI Ruby reference class integrated stereo amplifier. Use the integrated remote control input and output jacks to connect the SA-KI Ruby to other compatible Marantz components. An internal/external switch on the rear panel provides additional system control flexibility.
Pure Analog Design
The purely analog design of the PM-KI Ruby contributes to its noise-reduction structure and clean build. Rather than build the DAC into the amplifier, which would add noise within the chassis, Marantz built the PM-KI Ruby without one and then implemented the DAC in the SA-KI Ruby Super Audio CD Player. This eliminated interference with the delicate analog signals passing through the amp, maintaining an analog environment that’s as pure and clean as possible.
Low Noise Fluorescent Display
The deluxe low noise LC display features clear, easy to read alpha-numeric characters and is compatible with CD Text encoded music discs. Display can be turned off via the display control button on the remote. For enhanced user experience, bit depth of the input signal is now available on the front display of the SA-KI Ruby.
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.
More Than 60 Years of Audiophile Heritage
Founded in 1953, Marantz has a long and rich history of designing audio components embraced by music lovers and critical listeners around the world. Because Music Matters, the SA-KI Ruby carries the tradition of delivering a best-in-class listening experience for music and cinema.
