First appearing in the 80s, the Kiseki BlackHeart returns as the BlackHeart N.S.
It is still machined out of solid Blackheart wood but is now smaller size has it now sports the short 25mm long body style, like the Kiseki Blue N.S.
The motor is based on the same parts as found in the other current Kiseki N.S. models. Although, the Kiseki BlackHeart N.S. is the first to use a solid nude diamond mounted in and through the 0.28mm diameter solid Boron rod cantilever, instead of being mounted on it. We are told that this results in a mechanically better construction for better signal reproduction as well as higher reliability.
