Canon has lost the noise leadership a couple of years ago.
If you don't believe our findings feel free to explore the other sites - see e.g. the dxomarks for the 7D vs the D7000 or the K5 or the A580. Apart from sensor noise it's also inferior in terms of dynamic range here.

My goodness, Klaus. What did I write? Read it again.
That the 7D is a good performer. Nowhere did I make a statement about which camera is best in what.
Anyway, about dynamic range and noise, this is the SAME. As the dynamic range gets "measured" by the noise floor.
About the 7D/60D and its performance specifically: it is pretty equal in output (not silly measure methods) to the Nikon D7000 and Pentax K5, differences being very small. At higher ISO, the 7D shows a bit more noise, but finer grained, with more detail (the others show a bit of NR at higher ISO, resulting in a bit less detail).
As I said, the differences are very small, and one would be hard pressed to know which camera made an image. The dynamic range (low shadow noise at base ISO) advantage with the K5 and D7000 is lost at higher ISO's.
It is easily compared in the dpreview reviews, where you can have RAW samples side by side.
I wrote that the 7D is very usable at higher ISOs, and that is just true. The OP was mentioning using ISO 800 and 1600 with his A700 regularly.
And if for some reason you are a pixelpeeper who looks at images only at 100% pixel level, and do not like seeing some pixels having a wrong colour, then you won't be happy with the output of any APS-C camera. Or just need to know that at higher ISO's, under 6400, files clean up very well without loss of detail.
