Kiseki Blackheart N.S.

We proudly present to you our new Kiseki BlackHeart N.S.

Initially, the Kiseki BlackHeart model was introduced in the ’80s.

Like then, the body of the new BlackHeart N.S. has been machined out of solid Blackheart wood, but has now the smaller size ( short body ), like the Kiseki Blue N.S.

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

The BlackHeart N.S. is the first model using a solid nude diamond mounted IN and THROUGH the Boron cantilever, instead of mounted ON the cantilever. This results in a mechanically better construction for better signal reproduction as well as higher mechanical reliability.
