Thanks Nick, Your reply assisted me in a further search and I found this...

"When streaming MQA content there are 3 unfolds which must occur to receive fully rendered 192khz/24-bit MQA.

The first of these unfolds is handled by the BluOS app and will output up to 96khz/24-bit audio.

The next 2 unfolds are handled by the internal DAC of the Node to provide 192khz/24-bit audio.

If you have an MQA certified DAC connected to your Node 2i, you can enable this MQA External DAC option to have MQA content pass through the Node 2i untouched and allow your external DAC to handle all 3 of these unfolds."
Sadly this doesn't mean much to me!
