Many recordings have a hot top end. What you are hearing is likely an accurate rendering of the recording.
This may be true, and I agree that taking the recordings into account is very important when assessing a problem. I moved into a new home recently, and am in the process of taming some bloat from the bass produced by my rear ported speakers. During the process, I have noticed that in well recorded music, the bloat is very subtle at most. But in others, typically more popular soul and funk, etc., the bass was clearly boosted, and the problem is therefore much more pronounced.
