Schiit Gungnir via USB or l2s d(a)c with toslink/spdif


I’m a bit confused.

I love volumio. I currently use it for my headphone setup a magni / modi stack connected to the raspberry pi /w volumio.

I’m completely renewing my main audio set and use here a Schiit Gungnir dac with extra USB connection (C-Media CM6631A).

My question is if it’s better to use a

  1. l2s dac on the raspberry pi and connect it to the DAC via spdif/toslink.
  2. Or do it via the “crappy usb”.

(In case of the first, how’s that in compared to using the cubox? )
