Now that I've had time to tweak and enjoy my 5.1 setup, I was toying with the idea of adding another amp to my system to power a pair of rear surrounds for a complete THX or DTS-ES system. (I have a Pioneer Elite VSX-39TX that requires an external amp if you decide to use the rear surround channel). My question is for those of you who have made a similar upgrade: Was it worth it? Or was it more like "Eh, that's not that big of a difference...". I'm really interested in hearing from people that have had a 5.1 setup for a good while before making the upgrade to 6 or 7.1. ------------------ "We're hosed. We lost the remote."
