Marantz PM-KI Ruby Ken Ishiwata Signature Reference Integrated Amplifier
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 PM-KI Ruby amplifier
has been developed and tuned by a highly experienced engineering team
led by KI himself. . 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. 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 to
commemorate his legacy.

Laser-engraved Ken Ishiwata signature and Ruby motif, marking Ishiwata’s 40-year Marantz legacy
Celebrating 40 Years of Passion
Designed
to celebrate the 40-year anniversary of legendary Marantz sound master,
Ken Ishiwata, PM-KI Ruby features pinnacle performance that’s
synonymous with Marantz excellence. Complete with thoughtful
engineering, painstaking tuning and extensive listening sessions, PM-KI
Ruby achieves the elevated output worthy of its name. Elegantly shows
Ishiwata’s laser-engraved signature to commemorate the design and
heightened listening experience that honors the decades-long partnership
between him and Marantz.
Extensive Sound Tuning
Led by
Ken Ishiwata’s extensive, meticulous approach to tuning, the larger
Marantz engineering team applied more than 65 years of experience and
HiFi knowledge to create PM-KI Ruby, resulting in a final product that
is a testament to Ken Ishiwata and the Marantz legacy.
Marantz HDAM Technology
Marantz
developed its own discrete circuit boards called Hyper-Dynamic
Amplifier Modules, or HDAMs, to replace the chip-based amps used
elsewhere. Using discrete surface mount components with short
mirror-image left and right signal paths, HDAMs outperform the regular
integrated Op-amps dramatically in Slew Rate and noise level. The result
is much more dynamic, accurate and detailed sound. Over the years,
Marantz has developed different HDAMs to fit the particular requirements
of players and amplifiers. The PM-KI Ruby uses the latest high-grade
SA3 version. Combined with optimized circuit design layout and carefully
selected components, the PM-KI Ruby provides exceptional sound quality
and performance.
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.
