Separtaes = best
Rotel rec = better
Denon rec = good
Your Paradigms are pretty efficent so you don't need a lot of power but, having owned the 40's in the past I know the more current you give them the better they sound. The 3806 probably has more bells and whistles than the 1056 but won't sond as good. You have to decide what is important to you. Features or sound quality. As you probably know wattage ratings don't mean a whole lot. If it were me I would go with the 1067 (less expensive than the 1068) pre/processor and a 1077.
