No, today most will supply digital as standard. Certainly at the sorts
of amplification levels needed, analogue would be almost impossible to
achieve without feedback.

With digital ones, is there a propagation delay through the aid à la
DAB radio? My mum's losing her hearing a bit...

Not that I'm aware, Im sure I hear everything as it is spoken, at least the
lipreading will confirm.
