djones,
I was directing my comment to geoffkait who makes excuses for not doing testing. Blind testing/comparative testing of speakers, is not easy if you want great results. Dr. Toole's goal in those tests were to minimize the time between speakers to maximize the chance that testers could pick up subtle differences. For most other equipment, the changes are easier to make. Of course, according to some, fast changes "don't work" so for those people, it is even easier as you can take your time making the change and let them listen as long as they want.
