I have a 2i that I bought refurbished 4 yrs ago and upgraded power supply. That runs to a Topping D90 AKm version. I am getting great detail, non fatiguing sound. I will keep this til it fails.
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.
