Prof, yes; I voluntarily reviewed AVA's ABX Comparator (review is found at dagogo.com) with the express intent of 1. Seeing what an unusual device it is and how I would appreciate it, and 2. ABXing my ability to discern various products. I was aware that I was putting my "reviewer's credentials" on the line with one form of assessment.
I did the testing with it and passed solidly (i.e. 8 or 9 of ten in most trials) on every genre of gear tested except power amps. (The article discusses the results, and reveals that post-mortem I learned that I had similar results to AVA.
I figure that if I can pass ABX, which was not easy, I can tell if there is a much more obvious difference with Schroeder Method. So, yes, I think I have a good basis to discern a difference with Schroeder Method when I passed challenging ABX with power cords, ICs and SCs.
Suspicion is like inverse infatuation. :)
