I use a Rega wall mount bracket for my P10 but I don`t like the idea of mounting it to a wall at least my wall.
The walls in my place are drywall over metal studs and I`m not a fan of the metal studs at all for various reasons.
To me, my walls would transmit vibrations into the Rega wall mounted rack more than if I mounted the Rega rack to my component rack that sits on a tiled concrete slab floor. So that`s what I did.
I mounted the Rega rack to the back of my component rack using thin sorbothane pucks in between the Rega wall mount and my stand for better isolation.
Works great....so there`s an option for you if you need one,
