You have touched somthing here .... I have heard many audiophiles complain about the sound of some violin recording as or bright ... The violin is a bright .. often strident instrument when heard live ... Brass at time have that painful "bite"> The components that do reproduce these as they are heard in real life, are often deemed "sterile", "clinical" and my favorite "lacking in emotion"... Many highly regarded components soften those edges to the point that the sound the sound of those instruments is unrecognizable . Yet some audiophiles start attributing all kind of qualities to this kind of unfaithful reproduction .. I will spare you the epithets but romantic comes to mind ...
Often I wonder if the High End is about High Fidelity?
Yes but there is a difference between "high string sound" of the violin section and bright/distorted.
