Ayre QX-8: anyone using it?

Looking to upgrade from Blusound Node 2. I see Ayre QX-5 Twenty listed but not their QX-8. (Ayre does say on their product website that the QX-8 with the ethernet module is Roon ready.) In the ~$5k price range it looks attractive. I’m also researching the Aurilic Vega and Lumin U1/U1 Mini.

Does anyone have experience with the QX-8? Or with any of these in comparison to the Node 2?
