Kiseki Agaat Ruby

Stereo Moving-Coil Phono Cartridge

Kiseki Agaat Ruby


The Kiseki Agaat Ruby 4.5 is the top cartridge available to the audiophile customer and uses the same basic design as other Kiseki cartridges.

However, for this cartridge a very special SaCo magnet has been developed; the magnet used in this cartridge has a size 3 times the normal maximum size used in other brand cartridges. This gives a 35% higher output compared to the Bluespot and the Purpleheart.

The Agaat Ruby 4.5 uses a newly designed ruby cantilever which is very stiff; also new in the design is the use of a special so-called line-contact PF stylus.

The overall effect of these new materials and new techniques is very clear and will be appreciated by dedicated audiophiles all over the world.
