Mani, the neutral wire is meant to be "the" system ground, with zero potential, so it should not have any "input".  It is known, however, that many factors conspire to contaminate ground wires (including the neutral wire) with electrical noises, and ...

Ideally, you'd want to drive 35 feet of balanced interconnect with the low impedance source ( say below 150 ohms or so). How low depends upon interconnect capacitance. You can try Jensen output transformer to convert SE to Balanced at the phono-stage...
