It seems the judges might actually be qualified to comment, even!

I would like to have seen what material they were using.  Were the judges listening to the same material?  Using the same player and/or headphone amp?  Tests like this don't have a lot of credibility with me unless the test methodology is made available.  Good press for Klipsch, nonetheless.
