CDs are 16-bit, yes, and more than enough for our ears when used
properly. But because of the dynamic compression most music mastered in
the past 20 years uses only the top few of those 16 bits, which is not
enough. 20-bit is important for recording and mastering because you need
the headroom for signal processing, even when using the full dynamic
range, but it is absolutely unnecessary for our ears to have more than
16 bits. 16 is actually more than we need anyway, but it's a nice power
Putting 20 bits on and calling it HD, is like throwing developers at a
late project. You'd think it would help but you're not addressing the
core issu. At best it gives you a few years until the dynamic
compression cult "catches up" and restricts you to the top few bits again.

There's nothing remarkable about it. All one has to do is hit the
right keys at the right time and the instrument plays itself.
