  1. Device model : LG V30+ ROM version (Android 7.1.2, stock ROM) Why do you think your device supports Hi-Res (link to device features, etc.)? the LG V30 sports another 32-bit Quad DAC in place of the built in Snapdragon SoC solution – this time in all global markets. Ignoring that “32-bit Quad” marketing jargon for a minute, the DAC chip is ESS Technology’s ES9218P, a familiar chip in LG’s recent flagships. The chip features stereo quad parallel delta sigma converter channels with a 32-bit interpolation filter for a low noise conversion process, which ESS calls its HyperStream II architecture. For the spec insatiable audiophiles, the ES9218 boasts 2.0Vrms output, 130 dB SNR and -114 dB Total Harmonic Distortion, and support for up to 32-bit 384kHz PCM and DSD256 file formats. Of course, real world additional circuit performance, required drive from the amp, and input file type will affect these stats somewhat, but they’re impressive nonetheless. audio_policy.conf
