My suggestion is the UD-301, a bit more dynamic than my Uber/MB Bifrost so paired with the Ember its a better match IMO. But for the T1 I prefer it paired with the BH Crack and Bifrost Uber while I like the HE-560 is paired with Lyr2/Bifrost MB, the differences are very little but after a while with one or the other the differences become easier to notice. Just remember that this is a sonic preference and not a better or worse issue.
Thanks David, you are always super helpful. I ended up buying the Audio-GD NFB-1, but you can never have too many DACs right?
