My experience is with only the Soliloquy 5.0 and Proacs. Both are wonderful speakers, the Soliloquys perhaps more rich and dynamic, the Proacs more precise with better imaging. Either benefit from matching with a subwoofer, of course, though the Soliloquys seems to have somewhat better bass than the Proacs when used without a sub. The choice between them would be a matter of your preference in sound and the rest of your gear, and room.
If putting the speakers against a wall is necessary, another alternative would be the Soliloquy SAT 5, similar to the 5.0 but with no rear port.
