With respect, I take exception to "quality". It's how close to machine sent
CW it is that makes all the difference when trying to use a machine to
decode it. 

Just like computer generated voices, "machine perfect" is often not as
pleasant to hear or as easy to understand by humans as human-generated voice
or CW.
