Reduce the bit depth and the sound becomes more brittle, jagged, while
at the same time losing fine details.
I did some fascinating experiments with A/D - D/A convertor pairs
(hardware) that I designed and built in college. Digitizing sound on
2...4...6 bits can produce some funny sound effects. I wonder if there's
an easy way in software to shave off the lesser bits while preserving
the amplitude (I can think of a hard way, but I'm lazy).

The sampling frequency has influence mostly over the high frequencies.
What's gained at higher sampling frequencies is something I would call

But everyone's different and can perceive these things differently.
I guess you could do some experiments yourself. If you have a pair of
good phones, it's time to use them. ;-)
