Add the Vandersteen 2WQ sub
This high passes the Rogue and you are Bi amping
300 Watts on the 3 downward firing 8s in its sealed enclosure and your 55 Tube watts playing the 1 C which you will not recognize when you dial them in correctly
Much improved dynamics transparency and clarity with the whole system.
I do not know of any brand 2 way Box speaker at any price that can compete to this set up.
