I ordered an M11 because I've completely had it with my x5iii and M11 is the cheapest, most feature packed, player on the market right now (plus, I rely heavily on massive, extensive, playlists for listening, and I know how to transfer external playlists to Fiio Music....so there will be less of a learning curve). However, I have had such a bad experience with the x5iii that I'm much more skeptical of the M11 than most of the people on this thread seem to be. My experience with Fiio products is that they all seem awesome at first, until you start using them extensively and the massive bugs, headaches, and other annoyances that Fiio never bothers fixing start to show. So we'll see. I'm keeping an open mind (I kind of have to, since I just spent $450 on the damned thing, lol).
I'm hoping that the M11 will finally have enough memory and processing power to work well with other, non-Fiio, music apps. The biggest headache to me about the Fiio Music app is that all playlists have to be exported from a desktop music manager in .M3u form, then hand edited in notepad to change all the pathing in order for the player to recognize them, because Fiio Music App doesn't recognize relative pathing (or it didn't on the x5iii, anyway). Once you know how to do this, the whole process takes about 5 minutes to "find" and "replace all," but it's still an annoyance and an extra convoluted barrier to file transfer.
Does anyone know of a good android music manager app that will recognize relative playlist pathing from another similar desktop music manager? I own the full version of MediaMonkey's desktop app, and I know they have an android app, but I have never tried to transfer playlists from the desktop to android version, so I don't know how it would work (I could never get the MediaMonkey android app to work terribly well with the Fiio X5iii). I also use the JRiver Media Center, which has awesome playlist management features. However, I've never tried JRiver's android app (from what I understand, it's more a "remote" that just streams your music from your desktop via wifi, but I could be wrong as I've never tried it).
Does anyone else use playlists extensively and have a solution of their own? Do you know of any android apps that work with the M11 and recognize relative playlist pathing?
