What's left out there in the form of a 16x16 others than Crestron, ADA? I see Audio Authority has a nice one. Kramer has one but I hate the screw terminals for in/out connections. I can get Ada and will if I have to but it's nearly five figures there has to be some other option.

There are some killer AudioControl amps in place so it needs to be in the form of preamp and RS232 or IP controlled, IR as last resort. I dont do control 4.
