I’v read the titanium "can be hot", "tiresome", "shrilly". The soft dome to be "better", "tamed" by comparison.
Above mentioned is a very simplistic way to look at a tweeter. They can also do the opposite depending on how the speaker got designed (as a whole).
The edges of all the transients get put in place for your perception by the tweeter. Listen for those. Try this... unique track (i.e., not your typical mindnumbing audiophile track that got played at the shows) It could let you know if the Sasha is worth your while or not before you open the wallet.
