Different editions, pressings, and source media count as separate releases and therefore are not dupes. A rip from a different medium (e.g. vinyl) or release (e.g. a remaster or different pressing) of an already existing torrent counts as a different release. The dupe rules do not apply between the two different edition torrents, nor two differently sourced torrents. So if a FLAC ripped from a CD is already up, you are still allowed to upload a FLAC ripped from vinyl. And if a 320kbps CBR MP3 release of an original mastering of an album was uploaded, you are still allowed to upload a 320kbps CBR MP3 remaster.
