Built To Perform

Constructed to the highest standards with a copper-plated chasses to reduce mechanical and electrical interference

Masterfully Tuned

Complete with thoughtful engineering, painstaking tuning and extensive listening sessions, PM-KI Ruby achieves the elevated output worthy of its name.

Pure Sound

Built to leverage enhancements, maintain the purest possible sound and supply the power needed to drive the most demanding speakers.

Balanced Power Amplification

Drawing on design elements of the PM-10, the PM-KI Ruby is built to leverage enhancements, maintain the purest possible sound and supply the power needed to drive the most demanding speakers.

Current Feedback Amplifier

Current Feedback amplification is a well-known, Marantz-original circuit technology, thoughtfully designed to match the expectations of your Hi-Res music for wide-bandwidth and ensured high-speed reproduction.

Marantz HDAM Technology

Marantz developed its own discrete circuit boards called Hyper-Dynamic Amplifier Module, or HDAM, to replace the chip-based amps used elsewhere. Using discrete surface mount components with short mirror-image left and right signal paths, the HDAM outperform the regular integrated Op-amps dramatically in Slew Rate and noise level.

Marantz Musical Premium Phono EQ

Designed to deliver optimal sound quality by simplifying the signal path, the Marantz Musical Premium Phono EQ stage in the PM-KI-Ruby amplifier can be used with both moving magnet and low-output moving coil cartridges, thanks to a built-in phono amplifier.

High Quality Volume Control

Newly developed electric volume control uses the latest volume control IC to realize better channel separation, dynamic range and distortion-reduction, while retaining the operational feel of an analog volume control device. The amplifier employs new Marantz-designed electric volume control for high linearity and best-in-class channel
