Shielding ADC with High CMRR?

You are far better off measuring the CMRR at high frequency yourself if you actually care about it.

Getting 22-23 bits stable requires averaging many samples. Since delta-sigmas are slow to begin with, the net bandwidth won't be very big.

Sure, but it's assuming a lot to get from 17ish bits S/N to 23 bits without some extraordinary measures. He was talking about only having better than 1-2 LSBs of noise "inside a PC", so I guess I assumed this was a sound card sort of thing. I was asking for more information about the application. Seems incredible.

Nah, you can probably do it by standing on one leg till your brain goes to sleep.
