Personally I have no issue with posts re Walnut updates in this thread, or vice versa, as they share more features than they differ... so I guess people will be keeping track of updates to both anyway, and I'm guessing a proportion of those with the Z1 like me will have a V2 (so will likely be interested in any updates to either). My Z1 came by the way. I got it partly to use as a USB DAC with my Hidizs AP60 but cant work out how, or if it's possible so that aside...it sounds fantastic. Obviously very similar to the Walnut, not done a head-to-head yet so haven't determined which I prefer, its going to be close but something tells me the Z1 might (just) have the edge in clarity and overall SQ. Volume increases seem smoother, although I miss the satisfying on/off function of the volume control. I love the blue LED and the logo/fonts, yes I'm superficial and I love the oddly retro look of these players. And as I'm using single file full album WAV files on there, I like the ability to fast forward through them holding the right button, although seem to be unable to rewind back. I will try to do a proper head to head comparison at some point.
