Another anecdotal answer, which doesn't even quite address the question: The
difference between 1st order horizontal and 3rd order horizontal is easy to
hear for the common man.
Using 5.1, or some other arrangement?
The colloquial assumption or implication behind the use of the word
"difference" is that one presentation was better than another, but
strictly speaking all it says is that people noticed some difference.
Adding reverb makes a difference (some folk claim that directional cable
makes a difference), but more is not necessarily better. So it would be
good to have some elaboration of what form the listening tests took, and
what "difference" really means here.
This was one of the conclusions of the harpex
listening tests, and in line with previous tests by Stéphanie Bertet et al.
More interestingly for us, of course, was that you can get 3rd order
localization from 1st order material with the harpex decoder. But no decoder
can make meaningful 3D material from a horizontal source. So if I had to
choose between 3rd order horizontal and 1st order 3D, I would choose 1st
order 3D any time.
Personally, I am more than happy to accept a little dithering in my
localisation (especially as it is probably fairly well dithered in real
life already), if it means I have to buy fewer speakers. So I suspect I
would agree.
