Thanks.
A distribution amplfier from Geffen or Extron, or a host of other manufacturers... but most notably those two, will give you full signal quality to both locations. The product isn't a 1-in 2-out pass thru. It is a POWERED 1-in 2-out. From those companies you can rest assured that they are focusing on making sure the image is as clean as possible with as little noise as possible added to the signal.
I use 2 Extron distribution amplifiers and will likely be adding a switcher for component and composite video to my system.
