I just installed a new Mains cable arrangement in my system, I believe the overall noise floor of the system has dropped considerably.
My question:
I have a 4m attenuated interconnect between the TV and the Preamp. The TV has 2 wire mains input, i.e. no earth (I imagine it's double insulated ?).
I haven't tried disconnecting yet, but I was wondering if the 4 metre interconnect would be polluting the ground plane of the preamp, even when the TV is off ?
If it was I was wondering if some kind of transformer connection would be better ?, or even a A/D converter, they can be had cheaply, and going through an optical of my DAC.
Any thoughts on the subject ?
