Sort-of on-topic question - Is your LG V20 the H990DS model? Have you tried rooting, and installing alternate ROMs, and audio processing apps - like Viper4Android?
I know that the LG V20 audio amplifier has several modes of operation, depending on the impedance of the earbuds/earphones that are connected.
Have you noticed any significant differences in performance, when you connect your high impedance earbuds?
I've been seriously considering replacing my old Google Nexus 5 phone, with the carrier unlocked US version (model US996), rooting and installing LineageOS 14.1 (Android 7.1.2 (Nougat)), Xposed Framework, along with Viper4Android (or other, newer audio processing S/W).
It’s the LS997 sprint version, practically non rootable it seems. So sadly no V4A for me!
I don’t have any earbuds over 32ohms because I was using the 6s and didn’t want to underpower my buds. Maybe I’ll buy some higher impendance buds for the meizu if it can handle em.
In its stock form the non B&O tuned V20 is more ‘pure’ sabre dac without any colouration of sound. It’s clean and cold in low impendance but lacking some dynamics, in high impendance it has the dynamics and is more neutral-slightly warm (natural) so it’s better all round.
But honestly I find it too analytical-digital and I prefer detailed but analog sound with a fuller quality.
Also the stage presentation is slightly narrow and the midrange can be forward. I think the narrowness comes from some added crossfeed filter (or so I’ve heard).
There’s also a slight harshness in the lower treble as mentioned to me by @vladstef so it can come off a tad rough of trebley music.
There’s zero mid bass bloat on the stock version, actually it’s too subdued for my preference but most like it that way especially for bass earbuds.
V4A may be a game changer im not sure, the ‘audiophile smartphone’ thread guys would know though!
