Not going to argue your point, but can you explain why you think system-wide bitperfect is so important? If we assume FiiO Music is bitperfect, I’m not hearing any difference between that and Poweramp high-res output, which is definitely not bitperfect. I don’t use my mobile rig for critical listening, but I often listen to it late at night in bed when everything is quiet, so if there was a difference to be heard, I’d hear it then. Just curious mire than anything.
I'm sorry to have not explained better. I PERSONALLY need it. For everyone else, if you don't need it, you have so many options. So from my perspective it's odd that you'd pay for a device that charges a premium for a feature you don't need, since you'll use uapp, mango os, or whatever method to play your music.
With the m11 at such an amazing price point and from what I understand, it's on par with the r6 pro and Ibasso dx200 far more expensive devices, why pay extra when you're only getting a feature you don't need? Otherwise I don't see any difference between the 3, and fiio offers insane value then.
For me personally:
I'm sure I used music programs before iTunes but once I got an ipod, and needed a method for syncing my music and deciding what to add, I settled on play counts.
My top "favorite" playlist I'd build on my own actually isn't my favorite music, but what I actually listen to.
So I settle on using play counts to build my "top songs" playlist. I of course sometimes pick albums to listen to, but when I just want my actual favorite songs that I'll be happy each song, i use that criteria, and will push the play count on the play list higher and higher when I want to really zone in and jam out.
I also have smart playlists for listening to my recently added music, for arranging that music while I'm listening to it, and lists for listening to songs I don't listen to often, to see if they should still even be in the mix, etc. Etc.
I use iTunes smart playlist feature (and soon to be mediamonkey so I can use flacs) a lot. And I listen on my pc and desktop and want that data accuracately tracked. So I need system wide bit perfect android to be able to use a high end dap with the two median players that sync data to pc, rocket player and mediamonkey, that both don't do complete bit perfect output.
So ya. . I'm a weird case, but that's why it makes me also very confused why people are looking at system wide bit perfect devices but then only use apps that are already bit perfect. Although I do understand that many older devices are sluggish due to weak cpus so that could be a driving concern.
