Now I am certainly not the most knowledgable when it comes to electronics.... but I know that I always look for the Dynamic Headroom spec. Most integrated receivers don't list this spec...probably because there isn't much and providing it would do more harm than good.

Correct me if I am mistaken, but I am under the impression that the dymanic headrom spec/rating is a good indicator of the amps inherent power characteristics....especially in terms of reserve power (for spikes such as chees eluded to). Is my impression accurate?

It would be nice if manufacturers listed the dynamic headroom of their receivers.
