I had the Bronze already, so it was very easy to swap in the Black stylus.
Unlike most reviewers out there, I found it very easy to set up. No more difficult than the Bronze.
Also, unlike most reviewers, I found the Black slightly more laid back than the Bronze, but in a good way such that the music gels slightly better.
The Shibata stylus SHOULD be somewhat less detailed than the fine-line one in the Bronze, except the Shibata has a slightly tighter side radius. So comparing apples to oranges in a way.
Still early days though, but so far so good!
