If you're a fan of this movie

don't hesitate to buy the Synapse Films Blu-Ray/DVD steelbook. It has all the different audio tracks on one disc, even the original English mono track which to my knowledge was only previously on the New World Video VHS release. It's packed with special features and the picture quality is also the best out there, far above Arrow Film's release. The Synapse Films version is the way that Demons was meant to be seen and in this case, more importantly in my opinion, heard. The price tag is hefty, but this is the definitive version, and it's worth it. And it also comes with an amazing piece of memorabilia: A replica of the ticket the characters receive in the movie.
