Peter/Andy,First, an answer to your simple question: I use silver ICs. I believe I hear the difference and have a preference, but don't know why (from an engineering standpoint). I'll admit the differences I hear between ICs seems smaller than other cable differences, which are also small but not insignificant.
Second, I don't believe that digital offers audibly perfect reproduction. I think there is a different set of issues and tradeoffs in digital reproduction vs. analog. But as I mentioned in my prior post, I don't think the difference lies in averaging.
I don't really think the issue is continuity either. I wish I had the time and resources to really study it, but I suspect the difference between analog and digital reproduction mostly boils down to a few things: mastering, the effect of component selection on frequency response, differences in the nature of noise and distortion, and the audibility of steep reconstruction filters.
For example, variations in frequency response are much greater in analog reproduction, allowing listeners more latitude to tailor their playback equipment to match their systems and preferences. Mastering is also different. Although I haven't participated in one, I've heard of many demos where LP playback was digitally recorded and then replayed on the same system. The usual outcome is that the digital reproduction comes close to bridging the gap to analog playback but falls a little short, especially on less tangible qualities of reproduction. I suspect the remaining audible difference reflects our ability to detect differences in the noise "signature" among formats and/or sensitivity to a sharp cutoff in frequency response in or near the audible range.
Anyway, that's my guess. Thanks for sharing yours.
