Kiseki Purple Heart NS [New Style]
A legendary cartridge with a pedigree that spans three continents returns to the marketplace and to audiophiles everywhere, thanks to some fantastic entrepreneurs who believe in the LP! With the brilliant engineering efforts of Herman van den Dungen of PrimaLuna fame in the Netherlands, and the superb marketing and financial efforts of Kevin Deal of Upscale Audio in Upland, California, the Kiseki N.S. (which stands for “New Style”) has been renewed, improved, upgraded, and perfected. It will be sold through a select group of dealers that understand analogue.
The Kiseki PurpleHeart N.S. is a true beauty in every sense. Physically, it is made of rare Purpleheart wood, which turns from brown to a golden purple in direct or indirect sunlight. It sports a boron cantilever the size of a human hair, and a diamond so small that my 66-year-old eyes cannot see it, even with a magnifying glass. Though 30mm long, it weighs only 7 grams. Its edges are all right angles which make for easy setup. In addition, its strong .48mV output is a chip shot for all MC step-up devices that exist in the world.
