I have heard this cartridge on a couple of occasions. But it was sooo many years ago.
The cart retailed for 1K, as did the step up. That was in the late 80's early 90's.
AS I recall, the system excelled at detail retrieval. Was considered one of the finer cartridges of the day. Did not have the sweetness as a Koetsu Rosewood, or many of the low production Japanese cartridges.
If condition can be verified, I would buy it. Don't remember the compliance numbers, but I suspect it would be happiest in one of the higher mass arms, which was typical of low output MC's of that era.
Also look into re-tipping options. I would think that any of the 2000/3000 series of Ortofons would be a long term keeper.
