I have a Node 3, SMSL DAC, 2 powered speakers and 2 powered subs. From the DAC I have one coaxial cable to each speaker and sub. The speakers use the 2 RCA outputs, and the Subs use the 2 XLR outputs. Works well. Since the DAC in the Node is bypassed, I assume that the speaker and sub outs on the Node are disabled. All of the audio controls on the Node are disabled, so I control the volume on the DAC.
