A couple of things I have done to set my LP12 up is 1)place it on Aurios, that helps a lot and 2) brace the cabinet against the wall, preferably a stud area. I have a wooden block that is basically wedged between the cabinet and the wall, you actually want the wooden block to be under pressure from the cabinet trying to lean back toward the wall. I made one that is adjustable and I tighten it to make it tight.
