However, there are plenty that can handle +24 channels with the use of external preamps. The magic number seems to be "26", being "8 preamps, 2x ADAT, 1x spdif". Then there are some devices that provide 4x/4x ADAT I/O. I'm only going to give one device name since that's the only one on our supported device list: Focusrite Saffire PRO26. To get a more broad overview of the market I would suggest you look at the offerings from TC Electronic, Presonus and M-Audio too if you look for something like this. I can name at least 5 devices that do 24channel (spdif doesn't count for me) I/O if you have 16channels of external preamp. All at 48k of course.
