Jimmy:
I have an Audio Note 3.1X in my main system, butit doesn't have USB in, so I haven't tried it here yet. I'm considering the Devilsound DAC.
My Scorpios rock pretty good on just a few watts. Take the time to find the right position in the room with them. I found that in my other system they like a wider triangle, with the listener sitting closer than other speakers.
