I did some initial experiments with the D10s and Cosmos in the Cosmos thread, and got some weird 100 Hz noise when D10s was connected to Mac mini. Since this seems to be related more to the D10s and Mac mini I made a separate thread.
The noise profile, measured with macbook/E1DA on battery. Thus no ground loop. It was the same whether or not connected through the Topping HS01 isolator, powered with a separate USB/telehone charging PSU (it did not work without).
Looping the thing only via the Macbook looked like it should (with isolator):
So my question: is this what you can expect in "real use" - that measured performance drops significantly? Or is it anyway to fix this with the Mac mini to D10s?
