You really should do that test first before speculating about the outcome and 
your audience.

You would expect Audiophiles to spot the "super sounding" denon cables by 
listening, right? Yet a blind test showed the opposite. The test was to 
identify which audio take was played with denon-cables, el-cheapo cables from 
walmart and a bended cloth-hanger. If they where as good as they claimed, the 
denon-cable should get hits with probability significantly better then 1/3, 
otherwise its just luck.
Guess what the outcome was: There was a significant hit: But they spotted the 
cloth-hanger as the denon-cable. Thats what real experts do...

Do the listening test with as many people as possible and then show the 
results. And only afterwards start the speculations what the reason and the 
effects might be. (Thats called science btw.)

Have fun,

Arnold
