Apple only supports 44.1/16 max for music and what I remember, the earlier ones (and I think the one you were using is quite old) resampled everything to 48KHz with questionable math accuracy.
No mention in your posts of actually using a Chromecast, just some interest in it, but the DACs you have listed using I don't remember being well known for jitter reduction. Chromecast had high jitter on optical out and optical is more jittery in general.
I believe you just discovered recently a setting in the Node2i that fixes a known issue (I had same problem) and you use it in your headphone system, so have you truly done a 1:1 level matched comparison?
When people say they have "compared" things, there is more than going off memory. You need to actually do a 1:1 level comparison somewhat coincident in time. Most of your comparative examples are "troubled" and are you using your new unit in USB mode?
