How do you A/B amps in your system?

Comparing two different amps in my system of separates requires changing speaker cable connections, inputs, and sometimes system volume. Do you have any tricks you use to simplicity the switch over and minimize time between hearing one then the other? I know audio reviewers make comparisons between amps, but for me there is more subjectivity at play than say comparing two input components. Is this just the nature of the beast, or do you veteran listeners have tips and tricks!?

Like @ghdprentice, I use long term listening sessions for evaluation, not A/B back and forth.  Extended sessions give me chance to listen to a wide variety of music and get a good feel for it's strengths and weaknesses.  Some things really start to stand out after a few days.

Thanks for the thoughts, and @lanx0003 thanks for the exact tool. Of course on Audiogon we will have to debate the sound of the switcher! Lol

It dawns on me that the advice to listen long also allows for the amp to settle into the system (which seems like voodoo but I always notice that it helps).

I leave the main amp in place, put the new amp in the floor in front of it and hook it up.  I listen for multiple days unless it isn't really close.  I always do ABA unless it is obvious.  Somtimes ABABA.

Thanks @carlsbad2 . I do that in my studio, sometimes, but it's not an option in our living room 😄
