Kiseki BlackHeart N.S.

This is a short body Kiseki (25 mm long) which allows it to be mounted on a wider range of tonearms

This reissue of the original Kiseki BlackHeart is also machined out of solid blackheart wood, but is now in the short-body design of the Blue N.S. and Purple Heart N.S. SB. 

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