Ah looks pretty nice. I mostly use one of these: https://www.rane.com/catalog/product/view/id/2955/s/sl4-sl4/category/186/ … though sometimes one of these: https://www.denondj.com/ds1-ds1  Those are for DVS use though I would like to get a portable 192KHz+ recording device eventually, maybe something such as this: https://centrance.com/mixerface/ 

What do you need 192kHz for? There's barely much of a reason to go 96k even (assuming the converters are decimating/interpolating with decent quality). Those DVS things look nice though, I was thinking meh because RCA (unbalanced) and then I read "galvanic isolation".

Oh sure, if you're going beyond audio at standard speed then it starts making sense :-)

32bit ADC/DACs aren't a (useful) thing. That's just bullshit marketing. You can't get that level of precision without going to very expensive lab test equipment, at DC, nevermind AC! Those extra 8 bits are just noise.

96k is useful when processing is involved (sometimes), though often it makes more sense to resample around specific operations that benefit from higher sample rates (e.g. nonlinear ones) rather than run the whole world at 96k.

OTOH 32bit *float* processing makes sense for digital audio, as an intermediate format. I do all my audio work at 32f/48k with 24b I/O (96k not worth the overhead) When I coded FW for a DSP for my speakers I set it up as 24b I/O 32b fixed point processing (no float supp) at 96k.
