There are very few specialized recording interfaces that track higher than 24bit, and it's meant for preventing clipping, like for recording special effects or subject matter with abrupt or unpredictable transients. For music, there is close to zero need to track at 32bit. If you're gain-staging and tracking properly, there's no need for 32bit. Regarding MADI, again 24 bit is more than adequate for pristine audio.
24 bit, 96 kHz is the max specification it currently supports, though be aware that not all algorithms work at 96kHz. For a complete list of these, visit this link: https://www.eventideaudio.com/support/downloads/list-h9000-algorithms-wont-work-96k
Again, if you're tracking properly, making sure signals are not clipping, and using proper micing technique, there is no need to track at 32bits.
