I would sure hope so with Tidal. Perhaps there’s a hefty fee when it comes to Amazon HD. However, Bluesound/BluOS works with Amazon HD (and Tidal MQA) just fine. I use the Bluesound Node 2i with Audiobytes. What a great sounding setup—soundstage is insanely good. Of course I considered the Bluesound Flex 2i but do not see a lot of love for the sound quality. Decided to spend more and ordered the N2 last night (with the I can wait discount and my loyalty discount). Still spent more than I would have for the Bluesound product, but I know the sound is going to be excellent. I was assuming I could play Tidal MQA music on the N2; if not, I will try to cancel my order. I don’t need the Amazon HD as well, but I do want one of two. Hope someone can positively confirm.
