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!?
I developed a universal switcher that lets me compare any two pieces of equipment or 4 pair of speakers with adjustable volume matching. I also made an A/B/X, again, with level matching, but it is primarily for speakers. Both have wireless remote control with console override and "tell tales" that can be displayed, or not. That displayed Amazon box may not be what you want to use if you have a tube amp because some do not like to run with no load. My universal switcher takes care of that too.

@peterf6 My entire system wouldn’t be an option in many living rooms....I currently have 4 sets of floorstanding speakers in my living room. My amp is 7 ft wide and 300 lbs.

Yes - quite simply I reconnect the sets of cables (input ICs & out SCs) between 2 amps. Move the amps themselves, if space requires. You swap in an amp, and then listen AS NORMAL to your preferred music material, for a duration. Rinse, repeat. For an experienced audiophile, the sonic differences (more importantly - your interpretation of them) will at first manifest, then solidify / stabilize, and finally become quite consistent over time. Switchboxes meant to reduce swap-time is a false optimization. Such scenarios do 2 things:
