RE: "44.1 actually sounds better than 24/192"...

"It seems to me the higher the bit rate the less quantization is needed and less dithering to keep the distortion low so less noise?"

The word length also reduces quantization.

What dither noise does is make the least-significant bit (LSB) switch randomly to signal levels or resolutions at amplitudes less than the LSB. When played back, with classical "sinc" filtering, the resultant level of the analog signal is close to the original signal below the LSB. Without the dither, the LSB would not be triggered randomly at all, the quantization error would then increase as a result.

With longer word lengths (ex: 20 bits instead of 16), with the extra bits, the levels "below the LSB" are now handled by those extra bits, the low level signal is tracked more accurately than without the extra bits and using dither.
