"Redbook CD's have dropouts. When the missing data is too extensive for the error correction circuitry to interpolate, the sound is muted."
If you rip CDs to hard drive using EAC, dBpoweramp, or other secure ripper you will find that nearly all the disks rip bit perfectly unless they have been badly scratched or otherwise treated poorly. Most of uncorrectable errors are successfully hidden by the error concealment feature which makes it difficult to hear an error even if you know exactly where it is and are looking for it. However, playing Redbook CDs in real time the error correction circuitry may create a lot of electronic noise and that may degrade the audio playback quality, thereby accounting for different sound.
I would expect similar results with SACD playback, although I haven't investigated this. Unfortunately, the ripping solution does not apply to SACDs because of the DRM which is difficult to circumvent (and doing so is illegal in many jurisdictions).
