I had an ART-1000 and it was a very competent high end cartridge with a very cool/interesting implementation. I found it to lie between my Transfiguraton Proteus and Ortofon Anna (neutral to rich) which meant I couldn’t justify keeping it.
Later I got a Koetsu Onyx which replaced my Proteus.
I now have a Hana Umami Red, which I like a lot. It is more dynamic and detailed than my Anna and I decided to let it replace the Koetsu Onyx that I liked a lot.
Interestingly, the Umami Red had the "crudest" diamond mount, even compared to the awesome value for money AT ART-9. Perhaps that blob of epoxy is what makes the Red sound so good?
