1) Because it isn't obvious to me, I've never heard it.


2) Because that is the standard reply to anyone claiming to hear an
audible difference between two things, is it not?


Ok. Have you any well recorded 'light' music from the '70s? The sort of
album which has a variety of songs on it all with an orchestral backing -
and also close to the maximum time you can cram on an LP? Perhaps by
Streisland, Bassey, Diamond, Neilson - that sort of thing? Well recorded
MOR pop without electronic gimmicks? If you can't actually hear the
difference in quality between the first and last tracks on this sort of LP
load them into your computer and look at them on a spectrum analyser. It's
quite revealing.

I'm actually trying to think of one which has a reprise at the end which
might give an even more meaningful listening only comparison.
