Thanks. I think it comes down to whether I really want MQA. I've gotten by for 50 years without it LOL but I am paying for it so.........
I have no issues with the NAD or its DAC. But I suspect the 2 DAC's (one each channel) in the Cambridge are superior. But really the Cambridge should sound better considering the price vs. the Node 2i (not sure if the Nod2i and C388 share the same DAC however). I mean I know price isn't everything but people do seem to say that the Cambridge is a step up in sound quality.
Just not a lot of quality options for streamers at the price points I'm looking at. I really don't want to mess with RPi software though I could deal with it I suppose.
Anyway thanks again!
