KISEKI BLUE N.S MOVING COIL CARTRIDGE

Product Details:

Kiseki is the Japanese word for miracle, Kiseki is also a cartridge brand owned by Durob Audio in the Netherlands. Durob Audio was once a leading distributor of Koetsu cartridges in the days when vinyl was king. When Koetsu made a drastic change to its distribution policy Durob Audio developed its own cartridge in Japan and soon the Kiseki range became famous. In those days almost no one knew that Durob Audio owner Herman van den Dungen was behind the brand.

These and more stories can be found on the Kiseki website now that production, which has been on hold since the nineties, has started again. A batch of a 100 NOS (new old style) Kiseki Blues were made from old leftover parts recently and the speed with which they sold inspired the company to come up with the Blue New Style. Said to be an even better cartridge than the Blue NOS and available in quantities only limited by production speed. The length of the body has changed for an easier fit in most arms, the rest of the design remains the same, although the parts have far closer tolerances than they used to. The body is made from aluminium alloy and is 25mm long and weighs 10 grams, which combined with a dynamic compliance of 16 µm/nM means a medium mass tone arm will be the best match. The solid boron cantilever is tipped with a nude line-contact diamond stylus that is mirror polished. The VTA is 20 degrees and the recommended tracking force is a higher than average 2.4 grammes.
