whilst few people old enough to be able to afford this sort of kit
can hear the full range of frequencies present on a CD, let alone
anything supposedly "better".


Yes I have proved that point, as I found that my daughter could quite
easily distinguish between 16/44 and 24/96 flac music files when
played via my hifi, where as I struggle to do this.


How was one of the files produced from the other?


In the brief test I used two pairs of sample files downloaded from the
Naim website.


So I assume that you don't know how one was produced from the other in each
case. (I am also assuming the 'pairs' were from the same source recording.)

IIRC At least one person has analysed versions of such recordings and shown
that they have measurable differences that aren't due to a change of sample
rate or sample depth. Instead due to the producers deciding to "not level
compress the 'hi rez' version as much as the 'cd' one" or similar.

Hence in such cases a difference can easily be measured, and may be
audible, but actually tell you nothing about the difference in sample rate
or resolution being a 'cause' for said differences.

I just asked my daughter if she could hear any difference, and then to
explain the difference that she heard.


This tells you that she thought she heard a difference. But it doesn't give
you any clue to if there was any difference due to the difference in sample
rates or bit-depths.

Are the Naim files you refer to available freely? If so I'd be interested
in examining them sometime.

Slainte,

Jim
