If I understand you well, it seems you want to add an extra amplifier to drive your main speakers because you believe you have driven your Onkyo SR-703 to clipping levels, and that blew a tweeter on one of your Primus 360 speakers.
The SR 703 is rated at 100W/channel into 8 Ohms at 0.08% distortion, but that's way below clipping.
At 100W, your Primus speakers would be putting out 113dB at 1 meter - each. That's around 115dB give or take a few dBs if you were standing somewhere not too far from them, and it's way too high sound level for any normal person to bear, even for a few seconds.
A jack hammer at 1m is around 100dB. To give you an idea, 115dB is what you would get if you were standing in the middle of 4 or 5 jack hammers.
In other words, you are probably never going to listen to music at that sound level, and you probably didn't during your test.
If you do listen at these levels, then you don't need an extra amplifier, you need more efficient speakers, like the Klipsch, which are considerably more expensive than the Primus. Be warned that you can damage your hearing, though. Also the cat will leave the house and won't return, and the neighbors will complain...
Or get yourself some good closed headphones. With these you can damage your hearing, but nobody will notice...
The M-282 is rated at 105W/channel into 8 Ohms. That's 0.2dB louder than your Onkyo SR 703, so it won't change anything at all.
Imho you did not drive your Onkyo to clipping levels, you were just unlucky and one of the drivers or one of the xover components on the Primus 360 failed.
