I am looking at getting either the Panasonic SA-XR55s or the SA-XR70s for my bedroom. It will be hooked up some Panasonic speakers that are currently powered by 600W just like these two receivers output. I am mainly buying a new receiver because I would like to have optical inputs for Xbox and Playstation. I am also buying a new LCD TV. I am not sure if it would be better to have a receiver with a HDMI output for my TV or if it is really needed. I can save about $100 by getting the SA-XR55s. The current Xbox and Playstation don't even have HDMI outputs anyway so would it be a waste for me to get the SA-XR70s? If anyone has any other suggestions, please post.
