I have heard for years that certain brands had a thin sound, others were fuller or warmer… My personal claim is that if you unplug an amplifier and have another one in its place in a half hour, you don’t have the reference needed for a true A/B test.
Blind A/B testing sifts out opinions in a hurry.
Nowadays you can Audyssey or whatever most A/V receivers. At that point they are not flat, so yes you may have differences. Amps set to flat are very neutral.
If comparing 2 brands that are similar to begin with, then I agree it would be indistinguishable.
If you have a chance, try this: Setup a Yamaha receiver and a Denon receiver. Switch back & forth. Those 2 brands have the most different (opposite) sound of all the brands that I know of. It should be quit noticeable.
^ It has been many years since I done that test. I know Yamaha sound has changed some since then.
