Ok thanks for the info. There is actually a relevent article on Qobuz "
Uncovering the audio of the new LG V30 smartphone"
https://www.qobuz.com/GB-en/info/Qobuz-Vous/Uncovering-the-audio-of-the-new-LG179798
The article rambles on superficially (in the content of Audio quality)
To quote "The LG V30 smartphone includes an ES9018+ digital converter from the American manufacturer ESS, integrating four channels that can be used simultaneously (2 tracks in parallel for each stereo channel, which allows an improvement of the signal-to-noise ratio, Hi-Fi Quad DAC) or a single track per channel, in order to reproduce the audio read by this smartphone in Hi-Res or not."
Quite often it's what certain product providers don't actually say that "says" the most. E.g. If Qobuz did play bit perfect audio on a LG V30 they would say it. If it dosn't they won't mention it,unless specifically asked.
I have not used UAPP before. Is it a generally hassle free intergration if I use UAPP to play non- resampled music with Qobuz & UAPP?.
