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.

Wait a minute. Audiogon spell check turns tuberculin into tuberculin and you blame me?!?!?!
I typed your name by the way. Spell check turned tuberculin into tuberculin. See? Did it again! How is that my fault? And don’t call me troll. That is insulting. I am the troll master.

I must defend miller on this one.
He's a tool, not a troll.
"Honestly though, have a good time and just maintain logic, i.e., don't run the power cables close to and/or in parallel to any signal cables."

Parallel, or not, close to signal, or not, try not to run cables through the water tank.
