Bluesound Node 2i vs Upscale streamers

For those of you that have compared the Node 2/2i to some of the more expensive streamers like Lumin, Aurender, etc., what do the big boys bring to the table. Forget the internal DACs, I'm sure theirs beats the Node. I'm talking about using these devices as stand alone streamers into an outboard DAC. What are the differences you've heard?
