Hey Sam, it seems that you are worrying too much before the river runs it's course.
Don't sweat it man, everything will be just fine.
Just like I said before, just take your time and read the manuals of your components to get acquainted and understand how you do all the connections and how audio is carry through the various type of connections.
And also how to set things right from the menu setup for all the audio and video adjustments.
Keep in touch when you get your stuff.
And try to learn the most by yourself, so you have a better understanding on how things really work. You know, an update with the new high technology.
When I start in audio years ago, there was no audio forums, no internet; so I learn everything mostly from reading magazines, I subscribe to many of them for many years. And also by having friends that have the same hobby, and also by becoming friend with audio dealers.
Today with the internet, it seems that a lot of people are searching for an easy solution, but they don't learn the operational side of things...
And after their system is all set up, don't ask them any technical questions, because they are totally at lost!
Cheers,
Bob
