Plug all of your equipment into the same socket using an adapter ... this is probably a ground loop issue and using the same earth point for all your equipment (which a single point of plug in will do) should solve it.
Hum from devices.
Hi my setup denon dcd-510ae to musical fidelity v-90 dac to musical fidelity v-can to headphones. There is hum in the left ear headphones when everything is on but nothing is playing a song. Now when I either touch without letting go of my hand my dac or v-can, the hum goes away. But when I let go of my hamd the hum comes back. What can I do ?
