Separate Coax Cables for + and - Signal?
I have a dac that I've modified to use a shielded line transformer at the output. The transformers are beside the dac pbc with it's own fabricated diy pcb (trans use pins for pcb mounting)...
I used low capacitance miniature solid core copper coax cables for termination for the trans, also to shield the signal from AC line nasties (there's a copper braid shield for the internal AC wires). What I did was use the silver stranded screen wires as the (-/grnd) signal from the main dac PCB -> trans-> the RCA sockets....
The question is, is there any advantage of using seperate coax cables for the + and -/grnd signals??? I've seen this done beffore on rca inputs of tube amps using miniature coax cables.
A friend who made the transformers' pcb for me said that a single coax cable for 1 channel is better so that same interference is induced on a single coax cable, and it will cancel out some noise in the closed loop of the transformer....
Thanks for anything you guys could share.
