Oh yeah, you won't be hitting anywhere near 100WPC the vast majority of the time, and even when you do, it'll be brief. Far easier to damage speakers with underpowered (eg, 5 WPC...) amps than overpowered ones.
I think we're going to need a price range before we can recommend a receiver. With a range of ~US$1000, 1200, it's the Denon 3808, but I know that I don't have a price range like that!
Best way to confirm that it's the receiver and not the speaker? Hook it up to a different output on the receiver, just for testing purposes.
