I use a Behringer X32 rack with a couple digital snakes to route audio between 20 or so radios, software defined receivers, online broadcasts and other audio sources, and it's one of the most powerful pieces of technology in my lab/office.

The quality however of the X32 leaves a little bit to be desired. The power supply died in it due to fault capacitors (I was able to replace them myself) and the rotary switches on the rack unit itself no longer work (I remote control the box anyway) but.. I've been able to look past all this because the sheer power of the tech is unbeatable for my use case. Running a single CAT-5 connection from my detached lab/rack to my office in the house with 32 channels of AES audio is amazing stuff for me.
