 This is all getting a bit complicated for a human to do reliably.

No it's not actually. We're not solving the worlds problems here. We're listening to music. So there's either a large enough difference for you (and you only) to enjoy, or there's not. If you need to force yourself to hear a difference then forget about it and just enjoy the tunes. After all, that's what it's all about.

That's not what I was trying to get at, but rather as David said above designing tests that really prove something and cannot be invalidated is tricky, and what I was proposing was getting too complicated to be practical.

Your test is great, and good enough for most people, it's all I would do if my RAAT was stable now you have proposed it.
