Very sorry if I came across as condescending, apologies, and of course reading back through it now I see what you're saying. I think it was mainly a matter of not being clear in my comments and admittedly of being defensive myself; for instance when I said

, certainly including itsborken and mrarroyo, whose posts I often read for advice and opinion on this kind of issue. I'm just trying to lure you or anyone else who might have the urge to make some specific tests and comments on this matter, namely, whether there is an audible limit to the Move's detail on USB, a limit the D1 doesn't have. I believe I've read most or all of your posts on this, and unless I've missed something neither of you has gone into detail on this particular matter, though mrarroyo certainly has the experience to do so and itsborken has come as close as anyone to answering my concerns in post 59 above. Hey, my ears aren't in play here at all, I'm actually hoping to rely on your ears to answer my concerns.
Here's what I think would show this most easily: 4 short tests, one of each amp with a reasonably high end external source (multiple external sources would be better to dodge any synergy issues), and then one of each on its own dac, to show if SQ noticeably improves or diminishes in comparison to the external control. Essentially koto-in's idea but using the external dac for both portables. Namely, my fears would be confirmed if the move was better with an external dac, and the D1 was just as good with its own dac, or they would be dissolved if this wasn't the case.
In light of this idea, though, itsborken's experience with the opera and the move is disconcerting, as it sounds like they just didn't gel. I guess the source for my planned test would have to have a non-preamped line out (or at least one without gain), though even so it might be that I'm just hoping for the impossible, and results would vary depending on which dac was serving as control.
Hopefully you're intrigued enough and not too peeved with me to give it a quick shot if you have a few minutes to spare! best, FV
