>However, if these are different masterings as others are suggesting, then this test is moot.

No, because you can still hear the net difference between the two. So if one has "wider soundstage" you should be able to hear that in the result. If they are actually mastered completely differently, then you will get a net difference. But it would be interesting to find out what that difference actually is.

No. Put both files into an audio editor, flip the polarity on one of them, and if they're the same they should cancel out into silence. If they don't, what you're hearing is the difference between the two files.

It is literally the most scientific way of finding out if there's a difference between two bits of audio.

Which is why a null test is the only way to know for sure :)

Have you done a null test on them? That's the best way of finding out if there is actually a difference.

>2: it makes sense to me because if we can flip/rotates ia particles spin, why don’t we flip an antimatter particle?

"Spin" in particle physics isn't actually the particle spinning. Its just a name for a measure of angular momentum.

>why don’t we flip an antimatter particle?

Not sure what you mean by "flip". If you mean measure the spin, we can. A positron is an antimatter particle, and we can measure their spin.

>you’re probably not fun at parties

Why bother asking the question if you don't want / can't deal with a serious answer?

>if we can’t make antimatter

We can. It's produced at CERN all the time.

>why can’t we just make something that flips or rotates a particle?

That doesn't really mean anything as a sentence.

>I mean we could change it’s “behavior” right?

Sure? That's got nothing to do with antimatter though.

> I don’t know why but for me this makes a lot of sense

Because you're incredibly stoned? It doesn't make much sense in terms of the actual physics.
