Pal you have something I've not seen on an audio component.
A "LAN" connector is typically an RJ-45 8-pin style which is normally a balanced connection. You'll need to get the pinout from the manufacturer first. Then you may need to build your own cable. Does your DAC have a balanced input is the next thing you need to know, and what's the connector type? A Cannon plug (a.k.a XLR) uses pins 2 and 3 I believe for a balanced input.
