Between those two parameters I'd agree but I wonder about the lower end and some of the mid-range balls (NXT, AD333 tour) Many of both of these are now reasonably soft feeling cover wise and I bet there would be the same sort of inability to tell the difference as there was in one premium ball next to another. I wonder if GM fancied putting this to the test?

I agree. Its not a compression thing, with chips and putts its just the sound and with the softer covers of the balls you have mentioned and even things like Bridgestone E6 it feels/sounds very different to a cheaper ball.
