I asked this question a while back for the same reason. HEIL tweeters just sound correct to me as well. I was given Lawrence audio and Qualio IQ.
I am bothered by metal dome tweeters with ringing and harshness. And to my ears silk dome tweeters roll off or die quickly after 14K hz. Lose trailing edge and details.
But it seems like most newer AMT designs run the tweeters hot. I like to hear cymbals and tambourines but they don’t have to be the main focus. A triangle should not make you jump in your seat. I completely understand the original post and wonder the same.
