I have the Torus unit as well and love it but worried if it would be enough down the road with a pair of 7's. I have been using it with a pair of 3B2s and 9B2 with no problems. If you look at the dynamic power requirements associated with music/movies, you wouldn't simply take the maximum current requirements for the components and add them up to arrive at the proper power conditioner model.
I originally bought the Torus because of the very dirty power in our old neighborhood as well as several lighting strikes that knocked out components over the years. We have since moved and the electrical is much better, and all underground in our new community, lessening the risk of lighting. With the announcement of the cubed series and the description associated with the design parameters to reject noise/hash, perhaps I won't plug them in to anything but the wall.
