Thank you!
I provided a basic description and parts list. I thought that would be enough for the reasonably knowledegable and experienced do-it-yourselfer. If you are looking for step-by-step details, I don't have any. Following are links to my post on the project at Audio Asylum, rough schematic and other information on balanced power.

The most basic implementation would be a balanced isolation transformer with the primary attached to a power cord plugged into a 120V outlet and the secondary attached to a duplex outlet into which your components are plugged. For safety, a 20A breaker rated for medium or long inrush current should be used on the primary and a ground fault interrupter should be used on the secondary. With a standard household supply, the neutral side is grounded. Balanced power uses two "hots," neither of which is grounded. With equipment connected to balanced power, what would be the normally grounded neutral side is now "hot." Any accidental contact with that now hot side poses a risk of shock.

How elaborate balanced power is implemented depends on the individual. Isolation transformers are great at eliminating low and medium frequency noise but not as effective with high frequencies and could allow such noise to slip through. An EMI/RFI filter placed before the transformer filters high frequency noise beforehand.

If you are not a skilled do-it-yourselfer experienced in working with household electricity, I would advise against attempting such a project. You are still dealing with as much electrical energy as a 15A or 20A household circuit will pass. That is enough to kill yourself or cause a fire if you make a mistake.
