I have no experience with the new Bluesound product and therefore cannot directly answer the OP.
Doesn’t NAD make more expensive streamers than the Node, and still use the Bluesound OS? If so I would perhaps investigate that if I were the OP
Bluesound Node Icon
I currently use Bluesound products because of their multiroom capabilities.
In my main system I have a bluesound node N130 hooked up to a Mcintosh D1100 preamp dac.
Thinking about buying the new Node Icon but I would be by-passing the built in dual dacs so I am not sure if there is any reason to upgrade to the ICON?
If anyone knows the new ICON and can give me some advice I would appreciate it.
