Digital Output of Node x vs Wiim Pro

I recently abandoned a squeeze box as a music server and am auditioning a Node x and a Wiim Pro Plus.

I am outputting the digital signal into an older high end DAC (Audio-GD 7).

During set up the Wiim Pro offers the option of different resolution outputs upto 192khz 24bit. It plays a test tune, and if the DAC can't cope you have the option to go to the next resolution down. My DAC worked fine with the 192 / 24 output.

My question is what does the Node output at? There appear to be no options except for the proprietary MQA, which my DAC doesn't support.

Many thanks
