what would be a shield? metal - like a piece of flue pipe? It would be easy to tack it into place while wall's still open.
A good potion, perhaps 40 percent of the house 150 amp service, of the entire house's is running past this area. I've never noticaed anything but good clean sound, but as long as the wall's open - I figure putting soemthing up wouldn't hunt.
I also have some old really thick copper flashing.
also - speakers m60's will be about six inches above this run of electrical power.

Maybe you could run the cables through some kind of piping...check this info from Wiki. Hope there's some usefull info there.
Half of communication is listening. You can't listen with your mouth.

The problem of induced hum comes from running power lines in parallel, in close proximity, for long distances with your signal lines.
Crossing at 90° presents no problem. Speaker level signals 6" away from the power should also be just fine.
Really to induce noticeable hum, you need to wire-tie a 15' extension cord running a space heater to your line-level coax. Then you'll get something. Otherwise, with even a modicum of care you'll be fine.

Sound advice Chris, but you forgot to tell him while his wall is wide open he might as well put some sort of shielding up (I think that's what he's wanting to hear).

Scott, Chris's concluding paragraph is pretty much on target as to what would be necessary to cause audible hum pickup. Speaker wire is essentially immune from hum problems and connecting cables are typically well shielded enough so that minimal precautions as to wire locations are enough to avoid a problem.

Enjoy the music, not the equipment.
