I am not sure how you quantify a lot more audio, but we probably 
could not hear the difference unless you could squeeze at least
an extra 25-30 watts out of them, and even then it would be barely 
perceptible. My guitar amplifier with four EL34s is barely louder 
sounding than my other guitar amplifier with four little EL84s in it!
The tone is not as good, and it only really sounds louder
on the lower registers. 30 watts versus 100 watts is not that 
much when it comes to audio. It certainly doesn't sound 3 times 
louder! Not even close.
