You seem to be under the impression that you cant tell the difference in sound by just watching it on the TV...are you deaf?
No I'm not?
I'm saying the loss of the wonderful ear splitting spine tingling body shaking "can't hear anything other than the engines" noise isn't noticeable because it was never there on the TV coverage to start with.
The TV coverage is just different. The elements of the old engines that have been lost are the elements that were only there for those track side.
It's the difference between the engines sounding different and 'feeling' different.
