We have just finished a brand new single family house.  In addition to the electrical installation, the project included all the low voltage too. The owner is very happy with the great Martin Logan home theater zone driven by Marantz SR 7005 receiver, Russound whole house audio distribution with 9 zones and Polk Audio speakers, network throughout the house, Sharp 70″ and Samsung 3D TVs. All the equipment is nicely hidden in the media closet and controlled by the new remote from Universal Remote Control URC MX-780.  Panamax surge protection for the equipment and Cutler Hammer whole house surge protection has been installed as well. Most of the lights are being controlled by Lutron Maestro dimmers, bathroom exhaust fans are on Lutron Maestro timers.
