I'll offer another comment reinforcing the room/placement influence. I have a pair of VR4 GenIII's (I bought them from Driver) in a dedicated multi-media room. Before I bought them I was doing research, and spoke on the phone with Albert Von Schweikert about them vs the VR4 JR. Although he raved about the merits of the VR4 GenIII, his one caution to me is they may be to boomy in my room (14x20x8'). My experience has been the opposite - the bass is weak vs what I expected, and what it is in my other larger(and irregular shaped) room.
I also have Totem Mani-2s that I run with a Rel Storm III, which I run normally in the larger room, but have swapped with the VR4's. It's easier to place the Storm to counter the room influence what it is the VR4's, but it still take some doing to place the Storm for optimum bass. There's something about my room acoustics that I need to address one of these days (just been too lazy).
