So the 60D and 600D got 1/3 of a stop more light which more or less cancels out the advantage of the a580.

The 7D got approximately the same amount of light. Good. And on the surface it seems to have the same noise. But when looking more closely, it is clear to me that the noise in the 7D image is mostly suppressed by a lack of local contrast. If you increased the local contrast of the 7D image to match the local contrast of the a580 image, it would have more noise than the a580 image.

Exactly! By the way, DXO shows high ISO rating of A580 as 1121, 7D and 60D - 813/854.
