gentlemn, if there is a rolled off treble, there exists subtractive coloration.
depending upon the dip in the treble, there may be a loss of information.
one may miss certain low level musical details becuase they are recorded at a lower spl , because of the roll off.
thus, the warmth which is consistent with a roll off may eliminate some detail(S) on a recording.
can such a stereo system still be described as detailed ?
it would depend upon how one defined the term. no stsereo systems are perfect, so the designation of "detailed" already assumes that there exists something short of perfection, but how short ?
another words, how much loss of detail due to a dip in the treble still qualifies as a "detailed" stereo system ?
