@gnoworyta While I’m pretty sure no one wants harsh, I think I know what you mean. I was really seeking that upper detail and for that reason, folks here encouraged me to try AMT tweeters. That lead me toward Martin Logan’s Motion series and Legacy, but now I see there are variants in Wharfdale and Elac, among others.
The airy detail on the Martin Logan’s was truly jaw-dropping, but I was playing them in a room with very low ceilings (6.5 feet) and so there was a brightness there that was too aggressive. I really think that a speaker with better execution of the AMT tweeter plus taller ceilings might really have hit the magic spot you’re describing. Perhaps this one or something in their line? https://www.legacyaudio.com/products/view/focus-se/
Nice profile of the maker is here: https://www.youtube.com/watch?v=AAEefnhFA3o
And to be clear, I never listened to these because I could not get one into my home for an audition, plus, it really became clear that my ceilings were too low for them. But I did become fairly confident they'd be excellent. So, not a "fanboy" or anything, just pointing out where my research had me pointed before the ceiling problem deflected me.
