Disclaimer; I have no formal education on electronics or engineering of any kind.
Had a random thought about double blind testing. Instead of relying on ears, wouldn’t it be better to use devices that are not human? Bear with me. But if you setup an amplifier and speakers, with a microphone x distance away from speakers, play a recording that we will call control A. Record the recording through the mic and call it sample A Then make changes etc and play/ record amd call that sample B. then have a program that can display the differences between sample A and B. Everything else stays the same except what ever is desired to be tested. Does that make sense or am I striking out?

as in frequency response data ?
pretty much already done by humans.
they look at speaker data or amplifier schematic
and they can " hear" with their eyes.
you could analyze harmonics, frequency ,distortion etc etc
what you propose already exists in many forms

Two comments:
1 - it will be extremely hard to keep everything the same between recordings. Even moving some small items between recordings can make enough difference to swamp equipment differences.
2 - if you limit yoiurself to equipment excluding speakers, use Audio Diffmaker from Bill Waslo.

I have sort of done something like this using a little Tascam digital recorder with built in microphones recording a few minutes of music, not even the same music, on different systems in different rooms. It took a bit of courage to do. I then later sat back and listened to my recordings on a decent pair of headphones, I can tell you for free, the only one that sounded anything like "transparent" was a pair of big 845 se amps driving Quad ESL57, that was the only one that sounded like I was listening directly to a recording. The differences were more obvious using this method than it was in the room listening "live".
