Two identical systems playing into the same speakers and as always an instantaneous A/B switchbox.
No, it has to be one system to cut out variations in the other system, so that the *only* thing that changes is the mains cable. How do you propose that should be done?
An instantaneous A/B switchbox for the mains cables?
I've don't know if they already exist but I'm sure it could be done. You might need to get an electronics engineer or electrician to make one for you though.
But then you are interfering with the mains supply, which gives nay-sayers a reason to doubt the testing methodology.
Saying that an A/B switch box is interfering with the mains supply is like saying that the on/off switch on your wall socket is interfering with the mains supply. They are essentially doing exactly the same thing. They are both just a simple switch which breaks a circuit.
