On Tuesday night, I recorded a whole show with the archos from the AES out on the V3. I was running my D8 out of the RCA S/PDIF. I did the whole show at 48kHz. and while I haven't compared the two sources in detail yet, there are glitches throughout the archos recording. at intervals of approximately 18 seconds, this corresponds to Jamie's findings of 17.75 seconds for 48kHz... I was planning to run line-in for the second set, but it was a lot more crowded than it usually is , and I didn't really have the time or space to switch things up, so I haven't done any analog in recordings yet...
and it seems like a good thing that you've got a dialog going on. even if they don't want to improve it with 24/96 or gapless playback, I'd be happy if the get the bugs out of the recording...
In your emails, Jamie, have you forwarded them the url for this thread? maybe they'd find it interesting to read what we've been talking about...
