Was wondering if the LG v20 essentially becomes a pre-amp also when you run from the headphone out to system? A pre-amp and DAC.

It's been a while since I used my V20, but my understanding is that the phone has an "aux mode" that engages when attached to a line-level input ( > 600 ohm). This sets the output voltage to 0-1 Vrms which is appropriate for line-level. I believe the amp is actually still in the circuit, but yes, it's acting as a pre-amp.

That is what I was thinking as well. Thanks for the response. I am surprised by the quality and (quantity-now I know) of this phone straight into my system. Good stuff.

I can be used to front an amp or integrated for that matter, so yes, it can act as a pre. Although in my experience it is not quite up to the level of a good well vetted computer source and player sw and a great under $200 dac.

I wonder if I would hear a difference if I upgrade? I have LG v10 with Android 7, and G7 with Android 9. While the latter is clearer, more transparent and better detailed...the G7 is also bright and digital in terms of sound. I find V10 more musical and neutral, more body and bass, the sound is more balanced and even. Using Focal Listen Pro and Sennheiser HD 599SE, and CCA C12, all with the Duni 75 ohm adapter. I have 5x HTC 10 (some of them brand new, for a collection), but I quite enjoy the square, bright display of the V10, and it has no PWM (unlike G7, I find it atrocious). I know V20 has a PWM frequency of around 2.4 kHz. I do not care about IR and FM radio. I remember somebody wrote that V10 has better separation and sub-bass, compared to V20. I just love high PPI displays, this is why I own V10, G7 and HTC 10.
