An anniversary gift for audiophiles

Engineer Ken Ishiwata celebrated his 40 years of excellence at Marantz by designing this versatile, elegant, and powerful amplifier. The Marantz PM-KI Ruby generates 100 watts x 2 channels, and it's 4-ohm stable, so it can drive a wide range of speakers well. It features a fully discrete two-stage design with separate power supplies for the pre-amplifier and power amp, and the Marantz FCBS (Floating Control Bus System) lets you link and control up to three subordinate Ruby amps in additional zones.

 

Convenient connections

This amp is a dream for analog-loving audiophiles. There are six stereo RCA audio inputs on the back, including a phono input for use with moving coil or moving magnet cartridges. There's also a switch that lets you choose whether the amp will be used in basic stereo mode, or with a second PM-KI Ruby to bi-amp compatible speakers. The amp's preamplifier stage provides exceptional sound quality and performance, thanks to proprietary HDAM® SA3 circuitry.
