Yeah, but then everything that makes the NW-ZX1 a nicely-designed DAP goes out the window if one is going to turn it into a stack.
That is why I remain interested in the X5. The X5 looks (on paper, at least) to be self-sufficient, whereas the NW-ZX1 might not be, but that still remains to be seen (heard).
Yeah, I know, I am not willing to take a huge stack with me all the time when I am outside but if the combination is seriously magical, then I might think about it.
To be honest, I wish this dap to power my SE5way "good enough" (means not like HM901 balanced card levels but still not wasting the ciems) and I will be settled.
