Kiseki Purpleheart Sapphire

Stereo Moving-Coil Phono Cartridge

Kiseki Purpleheart Sapphire


This cartridge is developed out of the experience with the Purpleheart and the new Agaat Ruby 4.5.

Instead of using the costly agaat housing the proven purpleheart housing is used; also instead of the ruby 4.5 cantilever, the sapphire material is used for the 4.5mm cantilever.

The results are still a very high quality MC phono cartridge with the advantage of a lower price compared to the Kiseki Agaat Ruby 4.5.

The same pole pieces and stylus are used - all in all this is a very cost effective high-quality musical cartridge.
