CD Disc Drive

The SA-KI Ruby CD player has been extensively engineered and tuned by a select team lead by Ken Ishiwata, using over 35 years of CD player development. The SA-KI employs a new disc mechanism, the SACD-M3, developed by Marantz engineers purely for audio to play SACD, CD as well as CD-ROM and DVD-ROM. Toroidal transformers and isolated generates a generous power supply, combining with a high quality analogue output stage using the Marantz HDMAs, for clean and sophisticated design.

USB Digital Conversion

An asynchronous USB input handles high resolution audio formats up to PCM 32-bit/384 kHz and supports DSD 11.2MHz. All digital music is processed with the unique Marantz Musical Mastering technology, that upconverts digital files in to a single-bit datastream using the MMM-Stream converter. The high frequency signal produced is then processed by the MMM-Conversion stage in place of a conventional DAC to result in an analogue output. The USB and digital inputs are isolated to reduce interference and noise from internal components. The output stage of the SA-KI Ruby utilises HDAM-SA3 technology with low impedance output, while the all discrete dedicated headphone amplifier is constructed with HDAM-SA2


The front panel of the Marantz SA-KI Ruby features the laser engraved signature of designer Ken Ishiwata, along with a ruby motif to celebrate the 40 year career of Ken Ishiwata at Marantz. The SA-KI Ruby is available in a limited run of Black or Gold finishes.
