Marantz Ruby Integrated Amplifier & Super Audio CD Player

After 40 years with Marantz, Ken Ishiwata created the PM-KI Ruby integrated amplifier and matching SACD player.

This is limited to 1,000 units worldwide. The two are sold as an integrated set.

The amplifier features a fully discrete two-stage design with separate power supplies for the pre-amplifier and power amp — plus, a moving coil/moving magnet phono stage complete with Marantz Musical Premium Phono EQ circuit and Marantz HDAM technology for signal purity and exceptional audio quality.

The PM-KI Ruby is built on a vibration-resistant double layer chassis with thick aluminum panes for rigidity and features a laser-engraved Ken Ishiwata signature. Features include:

  • Marantz high-resolution preamplifier stage with proprietary HDAM technology
  • Switching power amplifier design derived from flagship PM-10 amplifier
  • Generous output: 100W + 100W (into 8ohm), 200W + 200W (4ohm)
  • Fully-discrete, two-stage design for signal purity, with separate power supplies for preamp and power amplifier sections to reduce interference
  • Toroidal transformer dedicated to preamp for clarity and powerful sound
  • Current feedback design with newly-developed wide-range circuitry
  • HDAM® SA3 circuitry for clean signal and optimal dynamics
  • MM/MC Phono input with new discrete Marantz Musical Premium Phono EQ circuit
  • Thick nickel-plated copper independent input terminals for CD and Phono, plus Marantz-original high-quality/high-purity copper-plated speaker terminals
  • Linear volume control with new electric volume system
  • High-quality construction with double-layer chassis, 5mm thick aluminum top lid, solid aluminum front and copper-plated chassis
  • High-grade, carefully selected audio parts: ultra-low leak current Schottky diodes, low noise complementary transistors, high-grade resistors, newly developed custom electrolytic capacitors, audio grade film capacitors and mica capacitors.
  • Laser-engraved Ken Ishiwata signature and Ruby motif, marking Ishiwata’s 40-year Marantz legacy

The SACD player includes an asynchronous USB input that handles formats up to PCM/DXD 384kHz/32bit and DSD11.2MHz.

By 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.

  • Marantz-proprietary SACD/CD mechanism “SACDM-3” designed purely for audio
  • Playback of SACD/CD and compilations on CD-ROM and DVD-ROM
  • Asynchronous USB input for hi-res audio up to PCM/DXD 384kHz/32bit and DSD11.2MHz
  • Isolation of USB and digital inputs to block noise from connected sources
  • Innovative Marantz Musical Mastering “MMM-Stream” up-sampling to DSD and filtering
  • Custom-designed 1-bit direct “MMM–Conversion” from DSD to analog
  • New analog output stage with Marantz HDAM-SA3 technology and low impedance output
  • Power supply with toroidal transformer
  • Dedicated headphone amplifier with all-discrete HDAM-SA2 construction

Marantz has designated 6 products as their "Signature Line". Custom Hi-Fi showcases and has in stock 4 of the models.
