Below is a quote from your page at
http://www.audiomisc.co.uk/Armstrong...airandmod.html 'And
listening to Radio 3 or 4 using the FM tuner demonstrates how much
nicer these can sound via FM than via DAB.' I quite agree but would you
say this is a result of the low bit rate the bbc uses or is an
indication of the inherent superiority of analogue vs digital sound
reproduction?

Alas I can't give a simple yes/no answer to that question because there are
a number of differences between FM and DAB in practice. Couple of examples:

FM tends to add some low order distortion, and also intermod, particularly
for stereo. Caused by the limited bandwidth, etc.

BBC FM has *level* compression applied in a different way to DAB. So the
dynamics are likely to be different. My impression is that this tends to
make the FM sound 'warmer' as it acts a bit like a 'sustain' pedel.


I wonder why human ears prefer the sound of a bit of 'sustain'? I
certainly do.
