TBH, this is where Id be thinking of running '100V line' kit round the
house....

That is what I did (I had some spare wiring from a former underfloor
heating installation).

Doesn't provide channel changing though. I suppose it might be possible
to extend the 'up' and 'down' buttons on the DAB radio round the house
too.

100v line isn't ideal these days. Not where you want a semblance of
quality.

It dates from the days when amplifiers were very expensive and sound
quality didn't much matter. It tends to be reserved for public address
systems these days.
