Bluesound has great support and will answer your questions. I had the same as I recently moved back to separates and had used a Node 2i a few years ago with success. My questions to them were since I am only using their product as a streamer, was there any differences between the new models and also were their new products improved in their streaming capabilities over the 2i and other older models. They said the streaming would be the same across the current lineup and that the new generation is improved over 2i/older models. I went with the Node Nano and it works well.
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.
