I find it hard to understand your motivation. (The dealer's motivation is a given.) What is it about the system performance that you find lacking? What would you hope to gain from the smaller JMLabs?
My immediate thought is that you might want more power from a heftier amp but, without knowledge of the rest of the room/setup, I am guessing.
