Time for dedicated outlets!

Thanks fellas, good idea to buy the materials and purchase labor and expertise only from the contractor.

You have to assume the electrician doesn't know anything about high end audio, and probably wouldn't believe you if you told him. Don't give him the opportunity to say you'll never know the difference, and just use a lesser product.

So true, even if he tells you about all the home audio systems that he's wired.
There are many tips on dedicated lines in the Archives.

As mentioned by cymbop, make sure you use an audio quality outlet. There are many discussions on Audiogon regarding quality outlets.

Use 10/3 romex, not 10/2. The 10/3 feeder has a full size insulated ground and the wires are twisted which goes a long way in rejecting common mode noise while the 10/2 wires are parallel and acts like an RFI antenna. The added cost of the 10/3 will pay back after you’ll most likely find that power cords will have a much less affect over stock cords, as has been my experience.
