I reckon an over-emphasis on one part of the frequency range could lead to a 'too much detail' verdict....because you'd be hearing too much of one part of the music.
But when well recorded music is played on a well balanced system - with nothing from top to bottom emphasised.....how can there be too much detail?
I like to be able to follow any single instrument, listen as a whole to the music or, preferably, do both at the same time. That's when the enjoyment is at maximum.
A nice high triangle, mid bongos, tight bassline simultaneously......bring on the detail.
