There is a difference
Home Theater Magazine is an important and SOLID publication both in print and online. Strong history and very powerful. To get your system featured there is a feather in your cap.
At the same time, putting the entire COVER of the magazine on a competing publication's forum is a little much.
The link backs help you. The PR helps you but why go so far?
I don't put links on their forums (although anyone out there who wants to will make FAST friends with me!!!) nor do I put large format images on their pages. There is a difference. I am sure you know that.
