On the flip side, if you prefer to use N10 USB audio output then I would recommend trying Alpha USB or Schiit Audio Wyrd 'Decrapifier' and draw your own conclusions on which connection sound better to you.
I do realize that Berkeley Alpha USB is an outstanding product, just not so sure that your setup will reap it's intended benefits.
I have done A/B comparison with USB and SPDIF connections and to my ears, SPDIF sound more transparent and robust. And by no means, I am saying that N10's USB connection sounded bad.

Like yourself, I am curious to hear opinions from fellow audiophiles as well.
