KI Signature
The KI Way

Few hi-fi companies, if any, can say that one person has steered their sound for four decades – like Ken Ishiwata does at Marantz. The KI Ruby SACD player and amplifier go beyond even the standards of past KI Signature achievements, embodying all of Ken Ishiwata’s experience and expertise. Therefor they carry Ken Ishiwata’s signature as integral part of their design.

The PM-KI Ruby Amplifier

The PM-KI Ruby is built with just one aim – audio performance – which is why it uses a fully discrete two-stage design with separate power supplies for the preamplifier and power amp section to reduce interference, and draws on the design of the flagship PM-10 amplifier with its moving coil/moving magnet phono stage and Marantz HDAM technology throughout for signal purity.

The SA-KI Ruby carries the DNA of exceptional ancestors, designed to take the CD performance of Marantz models to the ultimate level. Now there’s a new classic. The SA-KI Ruby delivers the kind of sound able to bring you closer than ever to your favourite music.
