I've been considering the node 2 myself so have been doing research. If I remember correctly, it uses a 32 bit dac chip with on-chip volume control and the math as per ess' explanation proves there is no degredation of sound, ideal if you're using the node 2 as your only source.
You could try that straight into the amp and ket us know. If you need the preamp due to having other sources, I agree with reubent's suggestion. It would sound best that way.
