How much amplifier power do you really need?

[RebelMan]

All this technical stuff above goes way over my head but just below that sit my ears. And they tell me more power means better sound. So can anyone translate the above so my ears understand please?

Yes. Your ears lied!  

It must be the two instead of one power cords that you use with dual mono that makes the difference then. My ears don’t lie. It’s like listening to my dog barking versus the labrador next door. It’s different.   Clearly

It was mostly a facetious answer I gave you, remember you asked.  

If you don't think your ears can deceive you then you clearly have not been exposed to the fine art... ahem... science... of psychoacoustics and psychophysics.
