This right here!I quite enjoy them for Classical music as well. Just adding that data point-- numerous genres are agreeable on these cans.
Listening on my T1.3 to some wonderfully recorded and mastered performances of Stravinsky by the Minnesota Orchestra. . . there's a stretch of albums, the 'Prof Johnson Reference Recordings,' done for HDCD that really just have some amazing dynamic range (even in good old fashioned CD quality lol).
<edit: great description and look at the DNR rating care of LoudnessWars: https://dr.loudness-war.info/album/view/85625>
The T1.3 really shines with this kind of range, it can go loud without hurting but retains detail. Pretty sure there was much 'Fletcher-Munson'ing in this can's design process...
