I was just thinking that nearly all portables now have a substantial
buffer. The DA converter is converting the buffered material and thus
not dealing with vagrancies in the process of the laser reading the
media at a perfect rate...  and don't most stand alone units now have a
small buffer to prevent skipping due to vibration... wouldn't it lead to
a different jitter situation than older bufferless players in regards to
CD-R media? Since the DA converter is reading the buffer regardless of a
CD or CD-R being played how does this impact things?

I guess here the software used by the buffer to error correct or re-read
the disc is a primary issue at this point. But data error and jitter
(the data is accurate but timing isn't) are separate issues

If the above is true can this be harnessed some how in the "this is not
a bug its a feature" tradition. Like if one has the intent to make
depressing or opressive music of some sort. Can it be intensified to
make it even more apparent?
