Somehow I think my stream is too strong or some noise will be highlighted when other noise is cancelled or the network clocks are banging into the audio clocks.

For the record. All my clocks are standard at the moment. No OCXO's or whatsoever

In those day's I didn't suspect the ethernet yet. So it was most certainly connected

In my own amateur mind you shouldn´t have a PC connected in any way to anything related to your HiFi equipment. I know that you can do a lot of optimization and run software like audirvana and stuff... But i don´t think that will ever touch a good audio streamer, remote controlled from a mobile device, with really good attention to noise floor. The noise floor potential of an audio streamer is rather crazy and the moment you hook something up to it, you are just worsen its potential to send a clean signal to the DAC. A cd player don´t have the same potential since there are moving mechanical parts involved, which is not the case if you use a good WiFi extender, to a streamer (both with great power), for exampel.

Due to the fact the AQvox became a problem. Which is connected between the Audio PC and the Streamer / DAC. I think the clock banging is the most logical explanation. Even more because even replacing the fuse in the Super 10 by a QSA Red will cause the same effect when using the normal switch.

Still what I don't get is when I connect several passive LAN  isolators in series to reduce the signal, which should be near perfect. That the sound will not only clear up, but it will also sharpen and lose strength, body, natural colors etc.  An explanation could be that the DAC must work hard to restore the weak signal

I have measured the PC parts in the Pink Faun streamer. Indeed they are not measuring good. It is still a PC.

On the ohter hand when people listen to the sound it produces they still pick it above the GrimmS
