You can hear the "space" when Steve Jobs is talking that a lot of the training material are from keynotes on a stage in a big space. That's why it sounds a bit "thin" compared to Joe Rogans voice which is probably mostly based on recordings in a studio with Joe being close to a microphone (and a proper microphone for recording)

I work in audio post production and would be happy to take a crack at cleaning up your source audio. There's a lot we can do to isolate the dialogue from the space and restore presence.
