Are you only playing with the 'master volume' control? Have you gone in and adjusted the different speakers individually through your reciever? What size room do you have? In my write-up concerning my Emotiva XPA-3 I specifically mentioned how much better the VP150 sounded once I fed it with a lot of juice. Of coarse I have over 11,000 cubic feet to fill, so I needed it. I don't know how much room you have, but if it's a large area, then pushing it with an external amp like I did might be the solution.
