Well after quite sometime i have bought Beyerdynamic Dt 880 edition 250ohms.
And also Xduoo-xd05.
Also i tested it comparing with LG G6 quad dac version.
Now i know why audiophile don't appreciate phone quality.
I blind tested it on my brother who is not an audio enthusiast and even he get so much appreciable of the difference of sound quality.
In short none of the current Mobile phones can replace a good external dac amp or a DAP.
If you guys are planning for superior audio quality plus portability , invest in something like Hiby R3 or Shaling M2S upwards. Or you can use external dac amp like Xduoo-xd05.
Then lg v30 thread is all hype train.
