Best way to A / B test amps? Use a switch?


I have two systems I want to do some a / b testing.  Instead of believe what you tell me I should hear, I want to see for myself.

I believe that the mind forgets what it heard 5 mins ago and internal biases kick in strong.  Therefore, I'd like to be able to immediately switch between two amps or two preamps immediately.

Any thoughts on how to do this without damaging one of the systems?

Running 2 systems myself. I build a switching unit with a break before make switch. It’s never a good idea to take a chance of accidentally connect 2 amps simultaneously. Something is going to give. Not hard to make and very cost effective. The switching is close to instantaneous. There are some switching units on the market you could try. Do not use speaker selector switches as the chance of having both amps connecting simultaneously is high in which case pop goes the weasel.  Break before make is the key phrase.
