First, a clarification: It is only the last few months that I have accumulated much better listening equipment. Since then, I have been listening very closely to music of all kinds, and I cannot believe the amount of distortion I hear. Now a casual observer would say, well, your gear might not be as free of distortion as you might think, however, I have some reference music that plays extremely clean and distortion free. It seems to me that if the problem was in the equipment, it would always be present. Instead, it is only in some music. What I often hear is a grungy grit around the mid to treble range, that sounds something like gentle clipping or over level recording (is that the right term?). It is often present in a whole song, and then not in the next song on the same CD. Now it is subtle. If I am preoccupied and well away from my speakers, I will not notice, but if I am tuned in, it's there. Am I hearing things? Is this something observed by others? Am I missing something? I realize that my previous gear was incapable of revealing such things (not to mention I might be much more intune with such things now) but I remain preplexed.
