Agree that this shouldn’t matter - other than phono cables. If you’re really experiencing a problem or want to be anal - a little trick from the world of Fire Alarm notification wiring - where this does happen often and is heard. It requires custom cables. Use a shielded cable. Decide which end has the larger transformer / ground sink. Land the shield on that end. On the other end, pull the shield back a couple inches over the insulation and make certain it’s not in contact with anything. Always twist your pairs.
it helps to know what your up against - AC induction vs RF interference. Either way, FA guys have been doing this for years.
