I agree with your thoughts I don't think the Icon streamer will be much better than the Node.
I also love the bluesound OS and the multiroom is excellent.
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.
