It all depends on how good the variable output stage of the CDP is and how it will match with the input impedance of the power amps. This is very important and could make or break a direct-to-power-amp setup.
Going power amp direct will be the shortest path and will require less interconnects, which is worth considering both sonically and financially, but it's not all that matters.
Technically all combinations you mentioned are viable, it will be for you to try them and decide what sounds best *to your ears*.
