FWIW I currently feel that the DAB 160kb/s version sounds quite poor. The
masses strings, etc, seem to have a 'sandpaper roughness' which I don't
hear with the BBC4 or FM versions. At times this seems to spread across the
stereo image like some sort of modulation 'noise'.

So my impression thus far is that the drop from 192kb/s to 160kb/s has made
a quite noticable change for the worse in the sound quality of R3 on DAB.
I'm currently listening to the DAB rebroadcast of the 5th and even as
'background music' the anharmonic sandpaper effect is at times quite
noticable. Since where I sit to type gives no stereo image, it just sounds
like anharmonic intermodulation distortion being added to the mid/hf
spectrum. Is this what other people notice?

Yes.

The puzzle is the change in sound quality is so marked.

I concur.

I've put in a complaint to the BBC and await the standard reply.

I am about to attend my first Prom of the season. If the Beeb have put on
the usual DAB display in the foyer I may have to be physically restrained.
If they have, perhaps we can get them under the Trade Descriptions Act
1968.
