Projector Power Cords

Copper will have a warmer/slower result in both audio and video if you use typical gold-plated plugs.  Silver, of course, is much faster, but also has its own problems.  I've found the absolute best is solid-core pure copper with rhodium plated connectors.

all of the power cords matter people dont realize that there is a lot more standard copper inside the unit after the iec connector, then a power supply full of standard parts then many more feet of copper traces running the internal power around the unit.  Ive helped design and build many pieces of high end electronics and theres never been one I have seen that was built any other way.  

I am having a one foot helix PC made for my projector.  

PS Audio. Thrifty too. Shielding must be done right or you're better off wirhout it.
