I have read about in-wall wiring on these forums but there is one question I haven't found an answer to. I want to run in-wall speaker wires and when i pull them through they will replace in-wall Romex installed as "future speaker wire" when the house was built in 1990. The speaker wire I use will be rated for in-wall use, but because it will be in proximity to many in-wall AC power wires, should I try to find a wire that is shielded? Most folks say that speaker wire doesn't have to be shielded, but I worry about interference so close to AC. I will have quite an investment in equipment in this room and only want to pull through wire once! Thanks in advance for your replies. By the way, other forums discuss this issue, but I like this forum because of its honesty and value-for-the-dollar attitude.
