I'm a Jazz listener. Some classical. Rock music sounds the same to me regardless of the resolution. First, as many have said, is the quality and mix of the recording.
System quality also matters. My DAC is a dCS Bartok, about $22K current list. System totals about $130K. With the proper recording quality, higher resolutions up to 24/96 can provide a wider, more open, airy sound field with better definition of instrument location. It's subtle but very nice. Above that there is little difference for me. But I'm an old guy.
To the member who reported a flatter sound at higher resolutions, I suggest you consider sampling some better quality DACs.
Enjoy the trip!
