The QS8 is probably a little bit behind the VP150...the center seems to be the upgrade choice over the surrounds if both won't fit in the budget. I don't know about 80 owners though....don't seem to hear nearly as much from them. I think a lot of people here that the 80 and 60 are pretty similar and that the 80's can go louder and they just save the $300 and stick with the 60's. As we know, they already go plenty loud.
