I stopped by my local shop some months ago to give a listen to the new Paradigm Persona flagships. I was met and struck with a strident and offensive top end. Being driven with a tube integrated this should not have been an issue. The issue as I found out several weeks later, was the extended break in period for these speakers which have a beryllium tweets. My Second listen was better but still grating. The third listen was almost 6 weeks after my first. They were adequately broken in. I imagine a lot of tweets made of beryllium have this issue.
In terms of Thiel speakers, I love their imaging and time coherent approach top speaker design, but yeah the top end can be harsh. I think the metal dome tweets could have been better rendered./designed.
