Mrtennis, yes, that would be a nice test for everyone -- I think we're deeply biased in the way we listen to our equipment. In the end what matters is the survival test: how long has amplifier x or speaker y lasted in my system? If it's more than 1 year, then it means our ears really like it. If after a few months I begin to question it, then it means there is something wrong. In my case, so far the two things that lasted the most are my EAR 868 power amp and my ESL 57.
