I also have a Node 2i and a Topping D90 and am very happy with that combination. But going back to the original question, I have these going into an Outlaw Audio RR2160. This receiver is a great box that does a lot of things pretty darn good. Totally in the target price and has lots of options. Class AB, phono pre-amp, tuner, etc. There is a clean one for sale here (not mine).
