There are different things that could be found through tests, but I don't think I've seen tests being really extensive.
The interesting questions to me:
- Can a difference be heard?
- If yes, are people able to reliably identify A vs B (as in, can people identify whether it's A or B rather that whatever they listen now is not the same as the last they heard)
- If they can identify a difference, which sounds better to them?

- Do different headphones give different results?
- Same question with headphones vs speakers?
