Serious Navigation Flaw


I like this app a lot. Way better than iOS iTunes. But every time I leave the app then later come back to it, when I navigate backwards from the song I was playing, the player goes back to the Artists tab instead of the Playlist I started from. Then when you tap the Playlists tab, it always starts me back at the top of the playlist list rather than where I left off. This is a real pain! I was hoping this would be fixed in the last recent update, but it was not. Ugh!!

Easily best iOS player but with opportunities


Absolutely awesome player.
Here’s the good: Any/all formats just about. Sends converted to DSD via a camera USB adapter to outboard devices in DoP, such as my Sony RSX-GS9 head unit with ESS Sabre DAC. The sound is spectacular.
Here’s the opportunity: Onkyo do please consider a landscape mode for the app and not EQ but the actual player. Several high-end car audio competitors and enthusiasts want to use this app for tablet in dash installations, except that means typically landscape orientation. Please! :)

Will Do Until Official Apple Support


Onkyo works well if one has audio files not (yet?) supported by Apple. It handles everything I’ve thrown at it (mostly FLAC, which Apple does not support and likely won’t)

I was loving VOX, still do, but I do not like “subscriptions;” a model they have adopted for many essential features. I would rather follow the Onkyo model, which is pay once to access “High Definition” encodings.

There are some things about Onkyo that bother me, but it is the dark UI design and my inability to see its on-screen widgets without my glasses. But that’s my problem so I won’t ding the app.

Good enough to call good stuff.

Enjoy the show.
