I have a ~30 ft run of four conductor signal cable (unshielded..it was cheap) from my (soon to be) DAC at my 'puter to my home stereo in another part of the house. In the attic I have to cross several Romex power cables. What is the best way to shield the signal cable? Can I place some material between them? How far away would they have to be? I know about the 90 degree crossing rule but is there anything else I can do?

I have been told to not let them touch and cross perpendicularly.

huh? Aren't you supposed to cross them at right angles when you can?
I'm certain you're not supposed to run IC's and power cables parallel.

JamesL, that's what mrarroyo said: to not let them touch and cross perpendicularly.

Your confusion would have been warranted if he used or.

Cross at right angles and seperate with a peice of foil backed stiff foam insulation Like the kind they use in RV construction. Or at least a thick peice of regular insulation

The 60 hz cycle interference should then be minimized
