How much power you need will depend on the speakers being used, the size of the room and your seated listening distance from the speakers. The less efficient and lower impedance the speakers are, the more power that you'll need. The louder you want it to play, the more power you'll need. If you have a large room and sit a good distance from the center and mains, the more power that you'll need. If you add all of this up and have low efficiency speakers that are low impedance and you have a big room that you sit a good distance from the speakers in, i wouldn't begin to think that 200 wpc was enough, let alone 100 - 120. Then again, if you have a reasonable sized room, speakers that are reasonably sensitive ( 90 db's or above ) and of higher impedance ( 6 - 8 ohms ) and don't expect to shake the house on a regular basis, the amount of power that you mention should be okay. Then again, there are differences in amplifiers even though they may be rated for the same amount of power.
With all of the above in mind, i would HIGHLY suggest investing in a separate sub & amp or a combo powered subwoofer(s). This will take some of the strain off of the other speakers if trying to achieve "thunder" in your living room. Sean
