I've got a similar speaker setup (Studio/60's, Studio/CC, and Studio/ADP's) driven right now by a Model 750. I've shaken the windows in the living room, and I don't think I've gotten close to feeding all 165W to the CC and ADP's. (I'm not saying it can't be done, because all it takes is turning the knob a little farther :-). I can relate to your concern, have so far not been able to stand to get my setup loud enough to actually endanger the center and surrounds. And any time you are listening to music only (assuming you're doing two-channel listening), the CC and ADP's would be safe no matter how loud you cranked the 100's.
