Dear Nandric, I know about those stories but as long as Van den Dungen remains silent we will never know the truth. It's not in my nature to serve both sides of an argument, but this might be an exception. Why?
Well, most Kiseki's (Blue, Purpleheart and Agate) were high impedance systems, which could point in the direction of Dynavector, whose systems were mostly high impedance. Probably because they used exceptionally thin coil wire, which required more turns. The Blackheart and Lapis on the other hand were low impedance systems (around 5 ohms), so different coil wire and possibly also magnets were adopted. The Kondo (then Audio Note) cartridges were also low impedance designs, so you could be right in believing that vdD asked his friend Kondo to built these top systems to his specifications. But this is pure speculation.
