OK. First, let me retract the word "arbitrary" since the channel track was selected for having adequate balance. I had earlier selected and submitted the pool of recordings, they were quite familiar to me and I not think that there was anything strange about the individual channel tracks played. After all, it was also with unknown speakers in an unfamiliar space.
My point is that you were using audio content in a way that was not expected to be used as a source. Selected for having adequate balance introduces a bias and immediately invalidates any test of preference.
It forces one to particularize one's assessments rather than to simply express a preference. One has to convince onesself of the reasons for the preference.
This kind of method does not lead to better choices for consumers - IMHO it is only a tool for speaker development that can not be isolated. Considering that the method was not able to help you to prefer between the two different Revel speakers I consider that it has mostly shown its limitations for determining preference - something many audiophiles and manufacturers openly say. It is why I do not see any advantages in carrying such experiences in such conditions. It remembers me of people carrying blind tests without carrying positive checks previously to validate the experience.
Remember that Harman intrinsically dislike reviewers - but they need them! All IMHO, YMMV!
