I am running some new wires in my house 1 circuit wil have X-10 usb powerline interface plugged into it. the other one will power my stereo equipment. I have had problems in the past with noise from the stereo power supplies interfering with X-10 reception and transmission. Is this noise transmitted over the neutral or the hot conductors. The reason I ask is it will determine if I run seperate neutrals back to the panel or 1 run 1 3 wire and share the neutrals.

Thanks
