Advice for mounting a TT shelf on a wall

Thanks for the posts guys, it points me in the right direction. Fortunately, I will be mounting it on a load bearing wall. Am I correct in assuming that half way up the wall may be another room node? I know to keep away from corners and other electronics. Want to get it as right as I can the first time.

 Matt, I misread your post and had to laugh. I read, mount it on a short door.  To each their own. Fortunately no one recommended a ceiling mount.

I couldn't be more appreciative of the comments/suggestions. The mounting bracket came in today and is as professionally made as I have ever seen. The finish is perfect, but most of all, the bracket is even better/stronger than it needs to be. So now, I will go out in the shop and choose among the wood slabs for something that will work well with this bracket. I like the idea about Herbies giant gliders. Saw them somewhere recently for sale.

 Attaching this bracket will have to be spot on as well. I want to get as close to the center of each stud as possible. And I am with the thinking that the mounting must make continuous as possible contact with the wall. I am still considering the height though. I still have time. 

Well, the shelf bracket is mounted, and I posted a photo of the temporary shelf for now. Man, this thing is heavy duty. Got it good and level too. I really do appreciate all the advice and reminders that were given. Will post another photo in my system page when done.
