Overview
Enjoy a fully discrete two-stage design amplifier with separate power supplies for the pre-amplifier and power amplifier for signal purity and exceptional audio quality, every time. Audio purity reimagined.
Key Features
- Built To Perform - Constructed to the highest standards with a copper-plated chassis 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 separation.
