Sabai,
Can you definitely tell if signal generator delivers 6.745Hz to the speaker? What if signal generator increases by 22.5Hz?
Can you DEFINITELY tell in blind A/B Transparent cable vs. zip-cord?
Can you DEFINITELY tell which note the wind's blowing?
Can you hear rock placed on top of your amp can totally change sound of it or any system component?
Can you hear fish singin'?
If you can, than trust your own ears 100% and you don't have to use your poor imagination(not good idea at all).
