Kiseki BlackHeart N.S. MC Phono Cartridge

*** CURRENTLY OUT OF STOCK ***

Kiseki proudly present the new Kiseki BlackHeart N.S. The Kiseki BlackHeart model was first introduced in the ’80s. Now, as then, the body of the new BlackHeart N.S. is machined out of solid Black Heartwood, but now has a smaller size (short body or "New Style"), like the Kiseki Blue N.S.

The motor is based on the same parts Kiseki is using for the other current Kiseki N.S. models.

The BlackHeart N.S. is the first model to use a solid nude diamond mounted both in and through the boron cantilever, instead of just mounting it on the cantilever. This results in a mechanically better construction for better signal reproduction as well as higher reliability.
