So my parents have an old bose 5.1 system thats been slowly falling apart over the years with various functions failing. Needless to say they want something new and they asked me as the tech guy. I basically know nothing about surround sound systems. They currently have a blu-ray player, an htpc, and an att cable box connected to the plasma tv and the tv connected by analog coax to the bose system. From seeing the set ups other people have it seems like I should be looking for some kind of receiver that can accept all the hdmi inputs and feed them to the tv while also providing audio? I basically have no idea where to start, what is good or what to look for, what brands are good etc. It just needs to be something that sounds good and doesn't require a lot of confusions since this isn't for me. The bose 5.1 system has small wall mounted satellite speakers and they like that which seem pretty standard but thats really the only thing thats a limiting factor.
