Keith , I concur with ALL of your statements in your post #1930 (above) All of it ! I will refrain from repeating your post word for word , I agree with all of it !
Mario ,
In much of the truly professional and more pricey of audio gear all that you might find are XLR connectors and terminal strips at all signal levels , more rarely TRS and TS and rca phono plug.
Especially older equipment, Think ; Rupert Neve , Studer , Ampex , Scully, Universal Audio,
SSL, API, MCI, I own some of this stuff. ___The list goes on and on ... ... ... ... _______
It is the operators responsibly in a professional setting not to cause a Train Wreck , this is what I have observed in the major recording studio, FOH live, and Broadcasting audio world. We are all just human after all and make mistakes. How much forgiveness one gets for these mistake is sometimes a measurement of how much of a clear track record that you have in that scenario and how much you are loved. ___LOL_!
