Ideally you should also use the computer on WiFi, when using Roon, to remote control the streamer. Again, to keep the noise floor low in the streamer and not being influenced by a connected computer in the signal path.

My thinking is now that you might have an amazingly low noise floor since it sounds awesome. The trouble is that a PC is not a stable environment and its noise floor will fluctuate and therefor you get this issues when you have such a low noise floor to protect.

Yes, I know about that. I have used Euphony Stylus on the Pink Faun streamer and Roon Roon as well. Euphony was the best. Still probably due to the clocks. The CPU was running at 0.3% at only one core. Without the clocks it was 8% how do you figure 🙂

I think a computer normally makes many mistakes.

Yes but also without the PC, a direct connection to the router causes the same problem. Same problem maybe as with the PC 🙂

Well now I have to get into the car. I'm visiting some audio friends in Germany

Have a nice weekend!

Thanks Tobias for thinking with me!

You just have brought a new idea to test. I will put the PC on another ground system. A PC is always leaking to the ground indeed. I have measurements of that. It's fed by the Audes transformer at the moment. When I put it on the normal powernet and connect it with an Lan isolator. The ground systems will be separated.

When I control Roon I always connect shortly to ethernet. While listening the control PC is not connected with the network.
