The Hifidelio drive actually is a DVD reader and CD burner. Reading an audio CD is absolutely no challenge for the drive, the optical structures on a CD are many times bigger than those on a DVD (the main reason, why the DVD's capacity is about 6 times that of a CD on the same area). So, if you handle your CD's with care (and I believe high-enders do), there is little reason to believe, that error correction is an issue here. We have testet many CDs: The Hifidelio ripped them all bit-perfect, just like Gigi said.
1's and 0's don't "sound". As long as the bits don't toggle (1's become 0's or vice versa) the external DAC gets EXACTLY the same data, so it's not possible for to digital sources to sound differently if the DAC is jitter-immune.
This is what digital (and information) technology is all about: There are no "small differences", there is no noise and no distortion. Digital data is either right or wrong. Otherwise, computer technology as we know it wouln't be possible. While it might be tolerable that this text or a picture has small errors, it is not for software code. If only one bit changes in software code, the software usually crashes instead of behaving "just a little bit different".
Verallgemeinerungen sind generell schlecht.
