For me I love the sound of Ritchie Blackmore's guitar. example: In his guitar solo on the song Anya, the solo comes to a crescendo with this wailing string bend, I just get off on that sound.
Not every speaker can produce this sound, IMO it depends on the type of tweeter. My first set of speakers were too soft on the high's and it took awhile of listening to realize something was missing. And that something for me is the difference between being into the music vs being bored.
Of course not every audiophile is going to like this type of treble. Perhaps to harsh or edgy for some, but for me I gotta have it.
