[net.audio] Dither, ways to improve CD sound

I recomend Carver Digital Time Lens (I know, another silly name).
I was impressed by the effect  the dithering and the channel mix manipulation
(A-B,B-A and A+B component of stereo and their realtive delay) had on a CD made
from a BADLY done ANALOG recording. The improvements were in noise level,
clarity and "warmth" and "realism" of the sound. The best thing about Carver is 
that you can switch on either the "lens" ( delay and channel mix) or dither
(2 separate spectrums/levels of dither) or both. The unit was $100-$200.

There was no appreciable effect on a GOOD digitally recorded/mixed CD's sound.

Am I a pedant for saying that noise added after decoding is not
dither? Its just masking noise, like somepeople add to their bedrooms
to help them sleep, and others add to their office environments for
presumably the same reason :-)
Noise added in coding produces the effect known as "dither".

It would be just like Carver to misuse names, genius that he is.
