And so the next major audiophile engineering challenge is, err, well what?

I can. And I think we're just going to have to agree to disagree on whether or not that distinction adds legitimacy or destroys objectivity.

Well the simple truth is the difference either exists or it doesn't - *if* the system is able to resolve it, and the test subjects possess the ability to hear it or not.

All the above are relevant and must be considered before a conclusion is reached which could be deemed objectively as fact. If the difference is subtle and not easily identified, which quite often it is with hi-fi, the matter isn't likely to be resolved within a few hours in a science lab
