I like the device below, 8 in / 8 out snake box going into double DB25. The website of the manufacturer even allows to customize each of the 16 sockets.
There are no preamps or anything so need DI box or genuine mic preamp but this gives full flexibility to customize the gain structure of each input separately. Fits nicely in the back of a rack for traveling. I wound up soldering my own and stumbled upon this shortly afterwards.
