Hello,
i am connecting an external amp to my NAD T778 and it gives me a slight but audible hum or noise. I tried a lot, even removing the earth (it got worse), removing the antenna cable that goes into the attached cable receiver, but there was a little improvement. I came across this
Will that help? Does it change the sound? I have tried a smaller version that looks like a cable with a mounted transformer and it reduced the hiss already. Any other thoughts?
