I have found there are a lot of “screaming tweeters” on the market.
@verdantaudio Oh yeah there are.
The reality is, to get more perceived detail in the sound profile manufacturers turn the volume on the tweeter up a bit.
From some careful examination, this is definitely one way speaker makers stand out. The other way is to make the mid-treble ragged, accentuating narrow bands. When you go from other speakers to the ragged, you go "Oh wow, I’m hearing things I never heard before!" even with the overall balance not as bright. The B&W and Golden Ear comparison in my blog post is a great illustrator of this phenomenon.
