Then there is something wrong with your system, or you have an active imagination. 16 bit 44.1 provides flat response to 20 KHz. In addition it provides adequate dynamic range for almost all music.
There are a few massive works like Mahler's Symphony of a 1000, that can marginally benefit, and I stress marginally, from a slight increase in the bit and sampling rate.
I general going higher than 16 bit, 44.1 is just a total waste of bandwidth.
