Analog connections are very universal. You don’t need to deal with handshakes between devices, sample rate differences, clock systems etc. because each device receives and outputs analog signal via mostly the same 1/4" jacks and plugs.
While a digital signal chain would have overall latency benefits and fewer A/D/A conversions, it just doesn’t matter that much with modern hardware.
