Early days yet but finding the M6 mostly awesome with some (hopefully temporary) shortfalls. The Shanling written music player is really nice looking. First stumbling block though is it doesn't change its language to what android is set to so its all in chinese, i was about to disable it before deciding to click through all its menus and voala, found english. Second thing you notice: its one of the slowest apps i've seen for scanning in music in. Now to playing , wow watch out fiio (and anyone else for that matter. this dap has the most bass i've come accross in a dap it actually sounded pretty good to me without eq (probably a first

) enabling shanling eq and volume is probably dropped about 6db. EQ frequency wise seems to work well but the change to the sound is a few seconds behind moving the slider which is super annoying and so i disabled the app and on to neutron. Next weidity, Neutron ARM8 64bit wont install, says not compatible, hmmm, wierd. Anyway installed ARM7 Neon. Couldn't copy my config from 64bit (could for theme/peq) Went and configured the generic driver, could only hear sound in mono whatever I chose, doh. Ok so left it on default hires one. This will only allow me to select 192khz compared to 384khz in M11/M11PRO N6II, DX200/220, R6/PRO.
Earlydays compatibility asside i'm seriously impressed. Using the peq settings copied from my m11pro I dropped 33hz down from 9db to 7db and upped 16000hz from 5db to 7db.
This is all listening on both devices from SE. This is the first time listening to the higher than normal spec AK4495SEQ and i'm unsure what opamps etc shanling are using but this is serious competition to the awesome M11PRO at an M11 price. Fiio may have been out Fiio'd especially if they can sort that ARM8 64bit issue, i'm sure neutron will catchip supportwise. Oh and I didn't mention it is noticably slower to boot than M11/PRO, R6/PRO and N6ii, hopefully they can improve that.
