I agree on adding LPS for improved sonics and or the only way to get higher performance out of the Node. I have since added the DMP A6 which outperforms any of the Nodes but you have to use a phone or tablet..
Difference between Bluesound Node, Node 2, Node 2i, NodeX
Audiogoners.
I love the Bluesound user interface Is the only difference between the different Node models the DAC portion?
Which would indicate that if you use coax out to an external DAC all Node models would sound the same through the speakers.
