Marantz Ruby Integrated Amplifier & Super Audio CD Player
After 40 years with Marantz, Ken Ishiwata created the PM-KI Ruby integrated amplifier and matching SACD player.
This is limited to 1,000 units worldwide. The two are sold as an integrated set.
The amplifier 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.
The 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. Features include:
- Marantz high-resolution preamplifier stage with proprietary HDAM technology
- Switching power amplifier design derived from flagship PM-10 amplifier
- Generous output: 100W + 100W (into 8ohm), 200W + 200W (4ohm)
- Fully-discrete, two-stage design for signal purity, with separate power supplies for preamp and power amplifier sections to reduce interference
- Toroidal transformer dedicated to preamp for clarity and powerful sound
- Current feedback design with newly-developed wide-range circuitry
