Sorry, I was editing while you were typing. But anyway, it's not now clear to me whether we are talking about just the sensor dynamic range, or some other dynamic range.

I interpreted the term "sensor dynamic range" to mean exactly what it says without the complication of the following ADC. Easier for me to visualize because my Foveon sensor has real analog outputs, 0-550mV (77,000 x 7.14uv/e-).

I was talking about the (digital) information that's actually possible to get from the camera, not just the sensor without any ADC. This is what's practically relevant and this is what I believe DxO uses. I don't think they de-solder the sensors and try to use them separately. I believe they extract information from the camera as RAW files. I'll admit that these are all just assumptions on my part though, I do not know what their methodology is.

Do pardon my mis-interpretation of "The dynamic range of a sensor is the ratio between the brightest and dimmest recordable light intensity". I missed the word "recordable". Tsk!
