It's hard to say exactly, but like every other Maggie, the 1.7 will take some power to drive them well, although how much power depends on the size of your room, the kind of music & movies you listen to, and the sound levels you prefer listening at.
I happen to have a fairly sizable room, probably not unlike your's if you're standing 4 Maggies and I like allot of volume for both music and movies, especially movies with lots of explosions.
But try as I might with my maggies and with the amps I've tried, in my room, by the time I got to a volume level that I felt was realistic, (which is really loud).... I lost a fuse.
Keep in mind the 3.5's and 3.6's have a fused midrange as well as a fused tweeter, so I did not always lose a tweeter fuse, sometimes it was a midrange fuse and perhaps you won't lose fuses quite as often as I did. And maybe you don't play your system as loud as I do and the lose of a fuse will be a rare occasion.
All you can go by is your short history with these speakers and for some reason you've blown fuses all the way around already.
Since I have no first hand experience with 1.7's in my room, maybe it will make you feel better to know that I've read that the 1.7's will play louder more easily then the 1.6's. But I never tried 1.6's here either, so I have no real basis for comparison to judge what that actually means.
You will just have to keep an ear open for blown fuses until you know your new system and it's limitations better. You will have to see how it reacts to things like explosions at the volume which you would like to listen to your system.
And one other thing, about your turning the CB-3HD off by the rear panel switch every night.
Every time you do this it takes the Casablanca a couple of hours after you restore power for the temperature of all of the electronics in the unit to re-stabilize.
Which is why as Steve pointed out, that it sounds better if left in stand-by.
Playing the system loud during this re-stablization period may also have some negative effect on the output. Until you are quite sure how your system reacts to different things, I'd leave it on 24/7 to rule out that the CB-3HD playing loud during this warm-up period has anything to do with the possibility of a blown speaker fuse.
I just don't think the MMG's and 1.7's were built stock to play at reference levels in a large room.
You might ask about that in the "Magnaplaner Owners Thread" in the Speaker section of the forum and see what their experience has been.
My guess is a certain amount of users will recommend having the cheap components of the stock crossover replaced. Something you may not want to do while the speakers are still under warranty, But probably a good suggestion in any case.
