I read 2 threads about these tubes and most everyone said something similar to what you have said. And I am overall satisfied because I think it is the dynamics which are causing what appears as brightness. And its just that one part in the song, not the whole song. Actually, I'm surprised at how much change these tubes have gone through. I've never had any tubes which changed sound as much as these, But I also see all the good qualities you spoke of about the tubes as well.
