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?

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.
@djones - thanks for the link!  strange that stereophile doesn't publish something similar for their measurements...
