If you go 218 to G65 using the 218 SpeakerLink Output to the G65's SL input you'll get a digital first unfold MQA from the 218 which will be processed by the G65 to its analogue outputs.

Using the 218's analogue output gets you full MQA which the G65 will add an additional ADC/DAC process to before the analogue outputs of the G65, which may or may not be to your taste.
