You could get away with recording it onto a tape. As with all duplication there is a samll loss of quality however I don't think it will be a significant loss. It will depend on your equipment.
How often you need to listen to the Paraliminal will depend on your goal. In most cases listening for 3 days and then seeing what happens then listening again with a new goal or a modified purpose for listening after your first experience is just fine.
