Streamer Upgrade Bluesound Node To Aurender N10

Just got into streaming via a Bluesound Node running Tidal and Qobuz, streaming from an iPad Air via wifi. Very impressed by the simplicity, convenience, incredible choice of music and sound quality. My question is; if I replace the Bluesound Node with an Aurender N10 will there be a noticeable difference in SQ?

Rest of the system is a McIntosh C52 pre amp, MC312 power amp and Magico A5 speakers. I feed the digital optical output from the Bluesound Node to the C52. A/D conversion is done in the C52. If I do upgrade to the Aurender N10, what is the best way to connect the system together? A/D in the Aurender N10 or C52, type of cable connection between the two units etc?
