SA-KI Ruby

Marantz SA-KI Ruby Ken Ishiwata Signature Super Audio CD Player with DAC
Key Features
Celebrating 40 Years of Passion
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.
Transport Mechanism
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.
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 analogue output. The MMM-Stream section of the process replaces the oversampling filters normally used in digital to analogue 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-analogue filter feeds into the familiar Marantz HDAM (Hyper Dynamic Amplifier Modules) in the output stage for optimal sound quality.
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. |
