Make Every Listening Experience Memorable: Marantz PM-KI Ruby Integrated Amplifier and SA-KI Ruby SACD/CD Player/DAC Bundle Fine-Tuned by Ken Ishiwata, Make Rapturous Music Together
Every music experience you have should be memorable. With the Marantz PM-KI Ruby reference integrated amplifier and SA-KI Ruby reference SACD/CD player and DAC, each one will be. Achieving rapturous chemistry when paired together, this bundle is unlike any other around. Developed, engineered, and fine-tuned by none other than 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 at anywhere near their price point. They also commemorate Ishiwata's 40th anniversary with Marantz and exist as living proof of his aural prowess. Experienced as a pair, PM-KI Ruby and SA-KI Ruby emerge as blue-sky instruments that transcend the notion of mere machines and manifest a rare mixture of realism, expressiveness, and naturalism that make listening an incomparable undertaking.
Ishiwata's unrivaled devotion to tireless critical listening – a pursuit that makes each musical instrument he creates for Marantz completely unique and distinguished from the products of any other manufacturer – remains connected to his fame for having one of the most astute ears in the business. His dedication to repeat testing, blending, auditioning, refining, and testing again until the sonics of a given component exceed his demanding criteria translate into otherworldly involvement. With PM-KI and SA-KI Ruby, you are investing in an integrated amplifier and SACD/CD player/DAC that serve as for more than examples of cutting-edge technology. You will own discerning devices that pulse with human soul spirit, provide life-nurturing journeys, and benefit from the bespoke tuning of a master.
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 with separate power supplies for the preamplifier and power amplifier section, it outputs a robust 200Wpc into four ohms and 100Wpc into eight ohms. This rare gem also arrives with a MM/MC phono preamplifier with a Marantz Musical Premium Phono EQ circuit as well as Marantz HDAM technology throughout for exceptional high-resolution signal purity and the cleanest pathway through the amplifier. A toroidal transformer strictly dedicated the preamplifier for added precision, proprietary HDAM SA3 modules for optimal dynamics, and a linear volume control with all-new components further ensure what you hear goes beyond the believable. Need total isolation? PM-KI Ruby includes a first-rate headphone output, too.
Marantz took nearly as many pains outside as Ishiwata did inside to make PM-KI Ruby just as unforgettable on the exterior. Built to last a lifetime, PM-KI Ruby touts a double-layer bottom plate, copper-plated chassis, 5mm-thick aluminum top lid, and a solid aluminum front panel. An OLED LCD display, remote control, and nickel-plated independent input terminals for CD and phono that abet high-purity copper speaker terminals further attest to Marantz's no-expense-spared mentality. The finishing touch is a laser-engraved "Ken Ishiwata" signature that complements a small ruby visual to commemorate this once-in-a-lifetime synchronicity of beauty, brains, and brawn.
Appointed with the same classy ruby motif and based on the flagship SA-10 and designed by the same Marantz team, SA-KI Ruby features a brand-new, in-house-designed disc mechanism strictly built for audio – the SACDM-3, which plays SACDs, CDs, and compilations on CD-ROM or DVD-ROM. SA-KI Ruby's asynchronous USB input supports high-resolution formats up to 32-bit/384kHz PCM/DXD as well as DSD11.2MHz. All digital music is handled via with Marantz Musical Mastering – a fully balanced proprietary technology that involves two stages: MMM-Conversion and MMM-Stream. In the former, dedicated master clocks guarantee all digital signals get directly upsampled to DSD256 (four times the SACD standard) without any need for sample-rate conversion. Because the output from the 1-bit direct MMM-Conversion process is an extremely high-frequency stream of single pulses, it's already an analog signal that requires nothing else than a benchmark low-pass filter to offer the purest-possible analog output. Enter MMM-Stream, which completes the enviably elegant digital-processing equation. The result: A sonically enthralling process that fully makes the best of digital music without introducing any artifacts that require more post-conversion processing.
In addition to 1-bit direct DSD to analog conversion, SA-KI Ruby also touts a brand-new analog output stage equipped with HDAM-SA3 and HDAM-SA2 modules as well as a low-impedance output. A toroidal transformer, dedicated headphone amplifier with all-discrete construction and HDAM-SA2 modules, and isolation of the USB from the digital inputs to block external and internal noise further elevates the engrossing fidelity on this gem of a musical instrument. And what fidelity you'll enjoy: Extreme textural detail, effortless dynamic contrasts, you-are-there presence, rhapsodic separation, and involving tones that put you face to face with your favorite artists.
What could be better? Marantz's five-year parts-and-labor warranty and our 100% Music Direct Guarantee crown reference bundle meant for singular listeners. Don't miss the opportunity to hear these extraordinary components in your own home today.
“Resolution, including richness of details and instrumental textures, was higher than expected, especially given these less-than-stratospheric price points. Good news for music lovers who (like me) enjoy multi-genre material: The Ruby components seemed to fare well across a broad spectrum of styles.”
