It's the speakers. I have had B&Ws with the same issues. They need to be played loud to make them shine. I would get out and demo speakers (your gear is pretty good and your set up is fine).
I would think smaller speakers are the wrong move. It sounds like you just want more bass at low volume. What is your budget?
Wilsons thump at all volumes (used Sophias are under $6000 these days).
