Hi John, I have not read the entire thread so apologies if there are any repetitions in my post.
What you want to do is a so-called ABX test where the crucial factors are the randomness and the double-blindness of the setup combined with a strict methodology of statistical evaluation. There is software available which does this for comparing for instance the results from different codecs or quality settings, see e.g. foobar2000. Unfortunately, this is not applicable here because I can't see a way to directly link foobar to controlling the Touch. Anyway, there are specialists in these matters at hydrogenaudio, http://www.hydrogenaudio.org. They have experience to setup a proper ABX test in even more complicated situations and are usually helpful if the intent is properly described.
