Kiseki PurpleHeart NS Moving-Coil  Phono Cartridge

According to Kevin, the Kiseki’s parts are from the Netherlands, Japan, and Switzerland, with final assembly in Europe. I hope Kiseki will be able to keep up with demand without sacrificing quality. The build-quality of all three versions I have owned over the years has been superb, and I have tried all three with a variety of turntables and tonearms. Though the Kiseki worked marvelously with my Graham 1.5, ET-2, and SME V tonearms, I prefer the cartridge in my current setup with the Tri-planar U2 and Merrill-Williams ’table. It gives my reel-to-reel deck some “real” competition, and both have a freedom from distortion, coloration, and dynamic compression that helps me relax into the music.

Is the new Kiseki PurpleHeart N.S. as good as the original? Absolutely. In fact, it is even better. Are current production cartridges better than the initial release in 2012? Yes!

Kiseki in Japanese means “miracle” and it is a fitting name to associate with the PurpleHeart NS. This moving-coil cartridge is relatively easy to set up, tracks everything I threw at it, has a relaxed yet detailed sound, and puts the performers in the listening room when mated to superb speakers like the Zellaton Stage, Wilson Audio Yvette, or the original Quad ESL-57. I am so taken with this cartridge that I’m already saving for another Kiseki PurpleHeart as a backup. I can’t be without this miracle cartridge ever again.
