Are your speakers placed close to a wall and far away from the corners? If so, try a 6dB cut when listening to music at 75dB SPL and above. Many older tracks were mastered before subs became popular due to HT. I suspect that those tracks were mastered & post-checked with consumer equipment available in those days. If there is a pro audio engineer reading this, correct me if I am wrong.
More bass up to a point, is probably better for HT. For music, it could sound very unnatural when the drum overwhelms the singer(s).
