Kiseki Purple Heart N.S.
When a small quantity of Kiseki Purple Heart N.S. cartridges arrived in the U.S. very few people were told about it. After all, they are very limited in their numbers, owing to the Kiseki way of building cartridges. No sample to sample variation in sound. Every one must be perfect.
Somehow, the word got around. The Purple Heart has been the number one, all-time favorite of Jim Hannon, the publisher and chief at The Absolute Sound magazine. He had worn his out years ago, and tried to have it re-tipped twice by some of the best the the industry, but could not re-create the magic.
When he heard he could get a new Purple Heart, he said “I want one” and didn’t even ask what the price was. At the 2015 Consumer Electronics Show in Las Vegas, he confirmed that not only was the magic back, but that the new improved Purple Heart NS was even better, saying “A lot of cartridges do great 2D, the Kiseki Purple Heart is 3D.”
Bob Levi, well-known hifi maven, reviewer, and president of the largest audio society in the world, had heard the news and immediately asked if he could have a sample to review.
