Best KEF LS50 Wireless connection to Node2?

Has anyone figured out the best connection for this combo? Should I go analog/RCA or optical digital? I understand one way will utilize the KEF’s DACs and the other the Node’s. I was thinking of going digital as I may add a turntable later and will need the analog input for it. Lifatec seems like the choice if I go Toslink. Am I overthinking this?

Thanks for any input.
