USB as output on 120?

[TapeSonic]

Hello. I am a week into owning my Deviate 120 and love it. I have a question... in the Advanced Configurator, I notice I can set the USB port to "Pass Thru." I am wondering if that creates an output at the USB port that I could then feed to an external USB DAC/headphone amp? I'm trying to avoid getting the preamp output. I had read somewhere that users are digitizing vinyl by using their Devialet. Maybe they are using the USB as an output? Thanks!
