What sample rate/bit depth is worth using?

[booshtukka]

I know this topic has been covered a bunch of times. Over optical, what's the maximum sample rate/bit depth that the Phantoms are actually able to honour?

For Dante I have 48k/PCM 24. Would 96k/PCM 32 achieve anything, or just be downsampled and a waste of bandwidth?

I'm using 48k/PCM 24 because that's the max my Symetrix can support. I haven't tried 96K/ PCM 32... have you toggled between the 2? Do you hear a difference?
