Bypassing dac on Cambridge 851N

Folks,

Posted this to Cambridge Audio, but thought I’d ask the same question to this group. I plan on purchasing the DirectStream “Senior”. I have a Cambridge Azure 851N that I would like to continue to use as a streamer to the DSS. Is there a way to bypass the internal dac on the 851N?

It looks like you have 2 ‘digital out’ options, SPDIF and Toslink.
