I would say that 24/96 is high rez and of archival quality. There are pros and cons to DSD vs 24/96 with many folks singing praises for both. The main draw back with DSD is that it is totally in the can. There is not much playback gear for raw DSD, thus the need to then convert to WAVE, which, in my opinion, you're better off sticking with throughout the entire process.
However, this may not even matter depending on the source of this tape. Is it a pre-airing audio recording of the show or a compressed for video soundtrack. If the latter, it is not worth the effort.
