Why is science just a starting point and not an end point?

Because you cannot ascertain by looking at a spreadsheet which of two amplifiers you will prefer. The only way to know what anything sounds like is to listen to it....”

I can get close enough with measurements that if I take 2 amps with specs pretty close I could never differentiate which is which listening....blind..with my ears and not my eyes.

Is that because of the gear being the same, or your inability to differentiate between the two?

Can we get a test of your hearing done so we can know what you are hearing?

And if we could have a scan of the electrical impulses in your brain while you are listening so we can all know exactly what you are experiencing while listening?

It's because listening blind I've controlled for my bias. Amps that measure fairly close it's almost impossible to tell them apart. One could even be a tube amp as long as it's measurements are close to the SS amp. One reason is speaker distortion swamps amps unless they are garbage amps. You'll hear the speaker and room not the amps.

So, you are unable to differentiate between the two.

Again, is that because of the amps, or because of you?

It's because the amps measurements are close enough that any differences the human ear can't differentiate over the distortion of speakers. Correct I am unable to tell them apart because of the limits of human hearing. Dolphins or bats possibly could.
