Use your computer if you have a streamer in-between. Better if your streamer uses fbre optic cable.
I now have 3 of the Sonore OpticalRendu streamers and they are great. Especially if you want to use a cheap noisy computer like me in a different room (and floor)
There are a few opticalRendu being sold on the used market. My recent one cost me $200 + an EtherRegen,
So, what I am suggesting means DO NOT use the Ethernet cable (RJ45) into your Integrated amp. Instead use a streamer that can isolate your network noise and computer noise from touching your DAC. My opticalRendus takes fibre from a network switch ($70) and converts it to USB, which I assume your DAC supports.
Of course, DO NOT connect your computer directly to the DAC using USB. The noise from the computer gets into the DAC.
