Physically connect a Bluesond Node 2i to a downline, stand alone Chord Qutest DAC

I have used both optical and coax (75 ohm cable), both sound great with my Yggdrasil. Since all 2i outputs are on at the same time (my integrated has no dac) I can run RCA’s to my integrated and coax to my Yggdrasil and A/B the Dac’s, prefer the Yggy, however the BS 2i is a good DAC. Lots of options enjoy. Also the Yggy doesn’t do MQA, nor does the Chord I believe, so with my set up I can compare MQA via the 2i direct to my integrated to MQA through the Yggy, with a partial unfolding, interesting option/comparison.

Another option is to connect your Node to your preamp via its analog outputs to one input, then run a digital cable to your Chord with the analog outputs of the Chord connected to another input on your preamp.  Both digital and analog outputs function at the same time from the Node.  Now you can directly compare the sound of the Node by itself versus the Chord sourced by the Node by simply switching the source selector on your preamp.
 I have done this in my big system.  All of my system components are powered through a Shunyata Hydra Triton except the Chord Hugo which is battery powered.  The Node holds its own, not quite as detailed but exhibits other attributes that are also compelling.
 I have chosen to use the Nodes analog outputs and use the Hugo as my dac for cd playback.  Your results may differ.

Thanks for helping.  If I run a digital from my Bluesound node 2i to another DAC (in my case a Chord) does that bypass or eliminate the DAC in the Node and let the Chord's DAC take over? 

Your other suggestions are intriguing though with switching and A-Bing the two!
