Usually 24/192. Don't know about this model but it's usually the case. 2. The same converter types (as for point #1) are used for A/D conversion. 3. There's usually less distortion if an digital out is used. Nevertheless, it's possible that you *might* prefer the distortion that the A/D conversion adds to the sound. 3.1 As far as I know, it's not a problem of "information loss", rather a problem of "added distortion". Try to minimize the number of conversions, that's my advice. :) 4. Difficult to say, it's really a matter of taste. I would say that the final clock should be the one nearer to the speakers' output (the Lyngdorf one, thus).
