Portable CD player as a transport !?

[GregGC]

Excuse my total lack of knowledge on the subject.
I know it sound crazy. The reason I thought of it was the 30-40 sec. anti-shock buffering they do. Doesn't that eliminate jitter? As far as the analogue section, no idea, and the actual transport probably bad too. Any way, No mater how crazy the idea it'll be interesting to elaborate on it. Again the 30 sec. buffering got my attention. If that offers any advantages, can it be implemented in a normal CD transports?

Thanks
Greg

Portable CD players compress in some sort of lossy codec that degrades the sound. It has to be decoded before sent out of the player. Jitter is purported to be higher with the buffer turned on.

Thanks a lot.

ALL cd players buffer the data from the disc, jitter isn't caused by variations in disc speed.

Yes, but the anti-skip in portable units is what enables the compression and higher jitter. The motor "kicking in" is also a cause of noise (jitter) in the digital output.

if you notice on some players there is a option for no antiskip...some anti skip and a mess of it.

Its possible that these players may not use compression in the lower anti-skip levels. would look into it.
