Marantz Ruby

Integrated Amplifier & Super Audio CD Player

In the 1950's and early 1960's Marantz was considered one of the ultimate brands. The Marantz Ruby returns the company to its superlative roots.

The Marantz PM-KI Ruby reference integrated amplifier, and matching SA-KI Ruby reference SACD/CD player and DAC, makes each music experience memorable.

The pair achieve rapturous chemistry. A bundle that is unlike any other around. Developed, engineered, and fine-tuned by Ken Ishiwata, the Marantz engineer who stands as arguably the most influential active figure in the hi-fi industry, the Ruby combination pushes the limits on what's possible with realistic sound, spellbinding purity, and artist-audience emotional connection.

Derived from the company's flagship PM-10 amplifier, PM-KI Ruby exclusively focuses on transfixing audio performance.

  • A fully discrete, two-stage, current-feedback design
  • Separate power supplies for the preamplifier and power amplifier section
  • Outputs 200Wpc into four ohms and 100Wpc into eight ohms
  • MM/MC phono preamplifier with a Marantz Musical Premium Phono EQ circuit as well as Marantz HDAM technology t
  • A toroidal transformer strictly dedicated the preamplifier for added precision
  • Proprietary HDAM SA3 modules for optimal dynamics
  • A linear volume control with all-new components further ensure what you hear goes beyond the believable.
  • PM-KI Ruby includes a first-rate headphone output for total isolation

Pure Analog Design

The analog design of the PM-KI Ruby contributes to its noise-reduction structure and clean build.

Rather than building the DAC into the amplifier, which would add noise within the chassis, Marantz built the PM-KI Ruby without. The DAC was implemented into 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.

Marantz SA-10

SACD/CD Player combined with the finest Digital to Analog Converter

Start with the Disc

Many modern CD and SACD players use computer-style DVD or 'universal' disc drives, simply because it's increasingly difficult for manufacturers to source dedicated 'music drives', purely designed for SACD/CD playback.

The Marantz solution is to design an all-new SACD-M3 transport mechanism, engineered solely for the best possible performance when playing SA-CDs, CDs and music stored on data discs.

The player mechanism promise the very best sound quality from conventional CD and SA-CD discs. The SA-10 can play FLAC files from 44.1kHz to 192kHz at up to 24-bit resolution, and DSD2.8MHz and DSD 5.6MHz, well as ALAC (Apple Lossless), AIFF and MP3 files.

Digital to Analog Converter

The SA-10 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.

Conventional inputs - optical and coaxial - can handle files at up to 192kHz/24bit. The SA-10's digital input section includes a USB-B asynchronous input for the direct connection of a computer.

This is compatible with PCM and DXD music files at up to 384kHz/32bit, as well as DSD2.8MHz, DSD5.6MHz and DSD11.2MHz.

DSD is at the heart of the way the SA-10 handles digital audio: PCM and DXD inputs are all upconverted to DSD at 11.2MHz using a proprietary MMM-Stream converter.

A high-frequency signal is processed by the unique MMM-Conversion stage, used in place of a conventional DAC, to produce analog output.
