With the KI Ruby Series Marantz celebrates the tuning guru and brand ambassador Ken Ishiwata’s 40th anniversary at Marantz. Couples that reach their 40th anniversary, celebrate this special day of their relationship with what is known as a Ruby Anniversary, a day that might be marked with an exchange of the precious red gems. Company Marantz and key designer Ken Ishiwata are making their forty years of partnership with this limited edition special series featuring an engraved signature from Ishiwata completed by a precious stone.


PM-KI Ruby
The PM-KI Ruby boasts 100-watt-per-channel and uses a discrete two-stage design with separate power supplies for the pre-amplifier and power amplifier sections, and takes a page out the flagship PM-10 amplifier’s book by featuring a moving-magnet and moving-coil phono stage with Marantz’s new phono EQ circuitry design.

Building on its analogue-only connectivity are six RCA inputs and two outputs, along with a 6.3mm front panel headphone output, while Marantz’s proprietary HDAM (Hyper Dynamic Amplifier Module) technology and copper-plated chassis are familiar inclusions on the spec sheet.
