Interesting - thanks for the explanation. In any case one thing which some people (such as the makers of this "memory drive" and a forum poster or two) seem to be missing is that error correction is NOT the same thing as interpolation. Successful error correction means (surprise surprise!) that the error is corrected, so that the correct bits get sent to the DAC. This is possible because there is redundant information on the CD, which allows re-reading and correction of an error. A few months ago I would have been surprised by Stereo Times' positive review of this thing, but not now after seeing the reviews of the Bybee "Quantum purifiers", the lack of any reasonable methodology for testing audio components, cable "reviews", etc. I've concluded that the audio magazines exist in a symbiotic relationship with manufacturers of high-end snake oil, and that the whole complex exists in a parasitic relationship to the rest of the world - or at least to those of us foolish enough to fall for such things. Obviously there are exceptions (SB!), but on the whole this seems to hold.
