Woops wrong thread

Your clearly don't know what's bit perfect and can't figure out what sample rate means.

AFAIK 48kHz is the default Android sample rate

Most of us uses as a DAC feeded by bluetooth signal. Obviously you can use it as a USB DAC, but there's better options, like FiiO Q3. UAPP is kind of worthless if you're using bluetooth, you can use the native app for streaming on Tidal instead.

No, the difference is input voltage (110 and 220V)

Qudelix explains that if your audio source is 44.1KHz, it's better to set LDAC to same. It's all about avoid resampling, which can mess with the audio chain, adding artifacts. Though Qudelix don't talk about bit depth, I assume it's the same: set accordingly to your audio source. Then you...

@FiiO what's the ideal configuration for use as an USB desktop DAC/Amp, to avoid battery degradation? Should I set the charge switch to On and activate battery protection?

Actually it's more loose.

K7 bluetooth is avaliable on AliExpress: https://pt.aliexpress.com/item/1005004880267508.html

@FiiO I'm using the Q3 as a desktop DAC/amp with my PC. In order to save the battery life, I'm leaving the charge switch ON. Is this correct?

@FiiO Does Q3 works with the micro USB cable CL06? I have an old Samsung S7, which uses micro USB port (it supports OTG).
