As you are testing setup positions, people tend to like the speakers a little closer together with less toe-in. When i moved my room around, i didn’t really want to hide the fireplace, that was never used. Though by hiding the fireplace, i greatly prefer the layout of the room and it blocks less of the view.
For shipping company, I like Averitt Express, because they know that my road is too small and curvy for a 53′ trailer and has smaller options to deliver to me quickly. Other companies deliver, one required me to drive 2 miles to the end of my road to pickup my delivered item, i can’t remember what company that is now. Besides this, i never had issues with any LTL shipping companies.
