How much space between cables is enough?


I understand that proximity between power cables and interconnects or power cables and power cables is a problem, but is there a rule of thumb as to how much space is required to NOT be a problem. 1/2", 1", 6"? Also, are all cables the same? I would assume that the higher the current, the more isolation, but belief and reality are seldom the same.

Power cables can run in parallel, closely, and should cross everything at 90 degrees. If you must coil power cables, do it far from everything else, and make the circles as big as possible.

Speaker cables should cross interconnects at 90 degrees.

Interconnects can run in parallel, closely, if they are shielded, like co-ax.

Closely ~ 1".  More than that is diminishing returns, IMO.

Interesting, I wonder what effect suspending cables from weak springs or 'floating" them on 6" inner tubes would have.

Try it and let us know.
Tony, I suggest that you stick with the physics until you have 6 figures invested. Physics suggests that putting anything ferromagnetic, like a spring, close to a signal line is a bad idea.
