I've not too much information but I'm quite a bit sceptical with the x10 due to what happened with the x3 relying everything in rockbox . And even if xduoo'd support more the x10 the zishan's harware appears to be superior on paper, having killing features as replaceable oamp or act as a DAC -that I think xduoo can't, but not sure-
I replaced the original oamp with the muses02 and the improvement was clear. Great sinergy with the stock zishan's hardware. With this upgrade this player can't be fairly compared with any other at this price point for sure, and and even at higher prices as well.
