Differences with CD ripping speeds audio folklore?

I have often wondered why people claim that lower CD ripping speeds produce a higher quality resulting WAV file. After all, wouldn`t people avoid using CD-ROM`s that routinely produce errors? Computer data demands high accuracy, or else programs may not work correctly or data may be inaccurate. In addition, CD`s are encoded with redundant data that allows the drives to automatically correct many errors, and detect those that it cannot correct. So why should reading an audio CD be any different?

So I conducted a test this morning. I used one of my old machines which had an older CD ripping program that allowed me to choose the speed of the rip. I chose 1x. On my newer machine, I used MusicMatch Jukebox to rip it, which averaged at about 25X. I transferred all the files over to my Unix machine and did a bitwise comparison on them. As expected, they are IDENTICAL.

So could the theory that lower CD ripping speeds sounding better be yet another example of audio folklore?

Michael, if you want me to explain it to you scientifically, I can't. I do hear the difference between copy and original. Although the difference is very subtle in most cases. In some cases, actually, a copy sounds better. Depending on the sonics of the original recording. Why don't you try it. And try this in both your stereo system and headphones if you have a good, high resolution pair.

How do they make originals? Do they copy them?
XRCD for example has a limited run of every recording. Because the original from which they press is only giving you capability to produce so many samples. Otherwise, they'd be burning CDs, don't you think?

It's probably not about the bit for bit precision of computer hard disk drives. It's likely more about jitter content. The faster ripping speed introduces more jitter. In my experience ripping with high speeds always sounds worse (flatter soundstage, less air en warmth).

Hi,

Don’t mean to hijack the thread, but similar topic. I have personally made & compared copies made using the Yamaha F1 burner ( Verbatim blanks ) .
They are superior to some original CD’s. The differences are quite noticeable. Only thing Yamaha has stopped producing this audiophile burner. Any suggestions on audiophile grade burners?

Thanks
