I've started to introduce the idea of also moving to a HDMI matrix with extenders solution as the house was wired with cat5e extensively (thank goodness). There are 8 other TVs that just have standard definition going to HDTVs so it would be greatly beneficial to do this at the same time as installing two a/v receivers. The customer obviously invested a ton of money in the original setup and I understand him wanting that original setup to work too, but on the other hand he is really just wants a the system to work properly. I've currently installed a Sony STR-DA5800es temporarily, what do you guys think of the ES line?
