No streamer, a computer plugged into the DAC via ethernet cable, and that’s it.
You must be using a swap cable to go directly from computer to DAC with Ethernet.
Would probably get better SQ using a router with a LPS with earth ground tied to DC common to wire to the DAC. Leakage is a significant problem across Ethernet interfaces.
If you cannot do this, at least get a EMO EN-70e isolator and put it in the cable.
