I see this thread is not so popular for a well regarded player that I believe still has quite a few issues,I just picked the opus#3 up recently and like it very much I have always love the burr brown dac and the build is very nice and top tier,I think the wifi is very weak and this causes issues with streaming ,DLNA works fine for redbook but not so good for bigger files,spotify works fine(probably why it was pre-installed)
Qobuz and amazon hd load fine but crash constantly after a minute or two and opus reboots,although I have found that if I download the music from these two apps then switch wifi off,I can play them offline without any trouble which is a big bonus.I do not like to use a lot of apps anyway and tend to stay away from full android devices which are now saturating the market.
I see audio-opus have disabled there website so I cannot see any more support for this player which is a shame,I tend to buy older players that have lost the love and can pick them up at good price and keep the ones that I enjoy I think this one is a keeper along with my DX100,QLS- qa360 and wm1z.
Is there any other apps out there that are very stable(Tidal doesn't work at all).
cheers Stuart
In my experience BandCamp works pretty fine, I used few times Spotify which (as you already mentioned is intended to work on this DAP), while have no experience on Tidal nor Qobuz on this, and for sure I wasn't able to play Amazon music on it (I mean I couldn't make it work from the start).
Just two things over this:
1) beware about avoid playing too much with installing and uninstalling, dont' launch the app just after you finish to install it, and above all do some factory reset to "clean up" the environment when you know what to keep, as that android OS imho will oterwise mess things up in the long run otherwise
2) Leave space on local SD, don't put much stuff onto it
3) look for maybe older apk of streaming services, as they might have APIs more "edible" for the player (my two cents)
Cheers!
