Kiseki NS series of cartridges


Anyone has experience with the new NS series? Wonder how it sounds...

To my knowledge only two models are produced from the available old parts. The Blue NOS with original parts and the Blue NS with some new parts. The Purple heart will be the next one. This means that from the Kiseki 'series' only the model Blue is (re)produced. This one should sound as the old one and there is info on the net about the (old) Blue.
