What tests would you like all speaker reviewers to do for their reviews?


What qualitative or quantitative tests do you think should be performed regularly on all speakers?  
Maybe like “how fatiguing is it with certain gear and cables?”  

Any other ideas?

@epz - really like this suggestion!  Group reviews with each listener describing their impressions would be very refreshing!
To all: Is there a published guide to understanding John Atkinson's standard measurements for the less experienced of us?
I think all speaker reviewers should attest that their hearing aids are all equally calibrated.
