Plutos: "Don`t forget that you still need to use some transport to load and rip your CD-s in to your hard drive. This all involves additional jitter and other problems."
Jitter only occurs during the actual decoding step, when the digital is transferred to analog. Until then, it is just another data file and you can move it around all you want. (It was certainly transferred multiple times on hard drives at the studio and production plant prior to becoming a CD.)
The only issue with a poor drive would be a read error, but that is not jitter. Read errors on CD are mainly an issue only if the CD is damaged or defective. Read errors on a disc in good condition are fairly rare (or no computer program would ever install and run.)
Most computer drives will read a disc multiple times to get rid of errors. Many CD players differ from computers in they only get one shot to read a disc correctly since the data is delivered in real time.
