@B9Scrambler is correct, although the Walnut duo are screen-less there is just something magical about the analog output of this rig! I was hesitant at first to bite on the F1 thinking it would kill that sweet analog sound of the V2 but sure enough it just turned out to be a transparent pass thru and only adding more juice for iem's/cans that may need a little push to make that potential
As sweet as my number one DAP is (Opus #1) this setup right here simply destroys anything I've ever tried that was touted to sound analog like
This photo title in my audio photo library is "Holy Analog Heaven R1F1V2"
I'm thinking what I was told of the reissue was right in the ProII that is advertised here on Penon and they obviously ran out of that version however I want to say as many goofy sayings the Chinese will put into their advertising they have never hit the mark closer than what's on the box in the photo at their link:
