I don't have one, but the Audient iD44 at $700 has 2 ADAT outputs, so the digital to analog conversion would be done by the ADAT to balanced analog converters you'd have to buy, which would determine sound quality for 16 of the channels. The other outputs are 4 balanced and 4 unbalanced headphone channels.
So a bigger Audient wouldn't necessarily give a sound improvement except for the 4 balanced outputs. Maybe I'm missing other options.
