Thanks for reply, but although the zs m1 is old, I believe the unit uses the early mz1 portable minidisc for recordings etc. I do have a early mint mz1 player and the recordings are perfect, so I think you are wrong regarding quality sound. I am still looking for someone who could repair my zs m1 as I said earlier, the minidisc on the zs m1 does not work and although the screen lights up there are no graphics. I need an electronics genius to repair it. Any offers ? Thanks
