Ahh snap! I just downloaded this and have been trying it out, was about to post something on here too I don't have any DSD files but downloaded a sample from https://www.oppodigital.com/hra/dsd-by-davidelias.aspx and can confirm it works. JetEffect settings aren't applied to DSD playback, and a little DSD icon appears at the top of the screen (shown in photo below). The new firmware also has an additional UI skin which looks like the skin on the larger screen Plenue players - largely black with highlighted orange menu items. I tried to take a photo of the transition but it hasn't come out so well - instead of the last-used menu item being highlighted all orange it's kind of a pixellated orange backing (since I'm guessing the screen can't handle the all-orange highlight of the larger screen models) - it's just visible on the 'Dawn of Ashes' line on the photo. Interesting they added the playback speed support - I don't think I've seen this on any other Plenue models. It was on my old J3 (and I think the S9 too). I found it handy as I played drums and would use it to slow down play and figure out what someone was playing for a drum line/fill.
