I still have all my vinyl. There's a warmth to the sound which you never got on the first CDs. They still sound great - and some of the recordings have never been re-issued in digital form.

For me, the great sound revolution is the ability of everyone to be able to do their own quite reasonable recordings for a few pounds. When I think of the money we spent hiring sound studios many years ago, and then switch on my Zoom H2 whenever I need it, that really is a sea change. True, it still takes skill and thought to make a decent recording, but the technology is amazing.

And I still have my grandparents wind-up gramophone, plus a portable wind-up gramophone fom the 1930s, plus a stack of 78rpm records. Wonderful fun!
