PS Audio Sprout 1st gen to external DAC

Hello Folks,
I’ve been happily using my PSA Sprout 1st gen’s analog out to my PrimaLuna EVO 400 tube integrated amp, primarily as a bluetooth streamer/DAC. It works fantastic.

I’ve been considering using an outboard DAC such as the Chord Qutest, PSA DirectStream, or Denafrips Ares, and was wondering if I can continue to use my PSA Sprout to send the signal to the DAC. In other words, can I use the coax on my Sprout to a DAC? Manual says coax is an input on the Sprout.

Put differently, is there a way to bypass the Sprout’s internal DAC and use it strictly as a bluetooth streamer?

Many thanks,
