It will sound as good as an average CDP with better than a Bluesound, which is almost all of them.
i would get a better dac
otherwise, look at your connection into the node - is it wifi or ethernet? might be worth trying a ethernet cleaner like an etherregen - that made quite a difference in my own system
btw, i have never had the node 2, but i have had (still have) the 2i and the new '3' - i don't think the digital bitstream sound of the 2i vs '3' are any different
