I wouldn't advise this! The stylus isn't playing a smooth waveform, it is attempting to play a staircase textured groove wall. The constant bashing of the needle between steps is analogous (pardon the pun) to applying an improperly light, downward tracking force with a normal record, also very bad. Besides the distortion, it wears down the needle very quickly with all the side to side groove bashing going on!

Have you ever looked at the analog output waveforms of a properly operating digital system? There are no little steps as they get completely cleaned up in the reconstruction filters. If there ARE steps it was either planned or something needs repair. Telarc LP discs in the late '70s and '80s were made from digital masters are were regarded as some of the best LPs you could get - if you like that sort of thing. Study the physics of the LP and you'll come to the conclusion it's a monstrosity of a mess and amazing that it works as well as it does.
