Too MUCH? Hardly. There is almost no such thing as too much power. I have driven a pair of Atoms with a Marantz PM7000, which yeilds a true 95w/ch, full range, and they had no problem unless driven hard. I am running Titans as surrounds right now and my amp is rated at 120w/ch, crossed over at 80hz, and they are doing just fine as well.
Thanks, after reading Paradigms website and the max input power for the Atoms was 50 watts I got worried. But I'm stupid, the lowest receiver I've seen recently was 75w.
Don't worry too much about the max input power. If you look at the "suitable" power, it shows a larger range. The likelihood of there actually being that much power present at the speaker for a sustained period is pretty low.
