Aplhifi, I think you're conflating several issues into one. A cheap CD drive is perfectly capable of delivering a perfect bit performance as far as data goes. If it couldn't, it would be useless in a computer. Corrupted data is no more useful to computer program than it is to a music system.
Of course, the drive may also be producing digital hash that gets picked up by the analog circuiting.
If the cheap and electrically noisy CD drive is side-by-side with the fancy audio electronics, it will likely influence the sound.
An, if a cheap drive has its output rebuffered, then it can't be blamed for a jittery signal - the buffer isn't doing its job.
If that cheap CD drive is in a computer far away from the stereo and is only being used to transfer data to another storage device, I become far more skeptical that there is an issue.
I rip my CDs to a music server (as noted earlier in this thread) and I've gone through several computers and optical drives over the years. I've yet to come across a situation where I can tell the difference between a file ripped on a Sony drive versus an Lite-On or other drive. Same thing with hard drives. I don't go "boy that Western Digital drive just doesn't have the same tone as my old Seagate...."
Of course, I keep my computer equipment away from my stereo in a different room.
Once again, in your next to last paragraph, you comingle two separate issues - jitter and noise. Jitter is a timing error that occurs when the data packet is converted to an analog sound. Jitter can be caused and addressed by several different issues.
EMI is a byproduct of the operation of digital circuits and other electrical devices. Good practice dictates that care be taken in circuit design to minimize that issue. It's tough to do that right in cheap products.
Finally, please do not put me in the "everything sounds the same" box. I've spent a lot of years picking out the equipment I like.
And I've also never said a word about MP3s in this discussion. The bulk of my collection is ripped to FLAC and I download very little music. Less than one-quarter of 1% of my collection is downloaded. Approximately 40% is material I've converted myself from LP and open reel to digital. (I'm in my 9th year of converting my analog collection to digital and working on another album as I type this.)
So to wrap this up, if you are going to have a CDP sitting on your system rack, it is important that it is a well designed piece of kit. If you are going to tell me that I can't get a bit perfect rip using the Sony drive in my DAW, then I guess we'll have to disagree.
