What volume did you plan to test at? Maybe do three tests - low, medium, loud?
How about including a plain-old joe-schmo type listener? "Somebody with a HTIB" kind of guy.
What will be the demo music? Hopefully not Alannis Morrissette.
That seemed hand picked top make the M22s look bad. Maybe the demo music could be a little more diverse this time? A little classical, a little jazz, a little blues, a little reggae, etc...
And since you're assuming the purchasers will also be buying the package deals, are you also assuming there will be a subwoofer involved - and thus included in the test?
I know my M60s do benefit from a little sub accompaniment (sp?).
