Can't help with the best tweeters out there but I have heard the Marten Dukes which have ceramic tweeters. The highs are definitely more transparent and detailed than soft dome tweeters but we were listening at moderate volume levels so I'm not sure if the ceramic tweeter would exhibit harshness at high volumes.
Maybe your tinnitus was caused by constant exposure to loud music rather than the titanium dome tweeters since I noticed you like to listen to your music at loud volumes from what you had written above. I used to listen at high volume levels, probably in the region of 110db(normally it won't last for more than 2 hours) and have been experiencing a slight ringing in my right ear for almost 7 years. According to the ear specialist, I am not suffering from tinnitus and it's just that my ears are slightly sensitive to loud sound. I was advised against listening to music at high volume levels to avoid this "ringing" and was told that there was no treatment to this phenomenon. Since then, I have not experienced any problems with my ears when listening to music at moderate levels, and I realized I have been abusing my ears throughout these years listening at insane levels.
The moral of the story is to practice a safe listening habit with whatever tweeter you ended up with. I also agree with Tvad in that the harshness can sometimes be caused by the recording or the system itself although some really high-end systems can be free from glare and harshness in the upper registers when the speakers are played at high volume levels. Sorry, the topic of discussion has swerved off-course.
