I hear crickets when I should be hearing some test record to explore treble capabilities? Why none?
For me, I use Brubeck records and listen for Morello’s cymbals. Or an old Art Blakey recording for, again, cymbals.
High frequency capability can make or break a system by making it fatiguing or boring. Top end also is a component of imaging as your ear/brain system uses this high stuff for localization. This stuff is important. Unsquare Dance is an acid of sorts for me for both high frequency quality and imaging.
A music teach friend of mine … we were listening to an Art Blakey record… or was it a Clifford Brown record… anywho… my friend pointed out to me how Art was changing cymbals to better fit with the timbre of the soloist’s instrument . Shiny for piano… dull for trumpet. Interesting… nether thought of drumming like that.
