I have been living with the Lg V30 as a dap/phone for about 8 months. Take away: It’s great. All in one device, fairly neutral sounding, but nicely dynamic. Great portable solution when you can’t have a more robust solution. Downsides: Not too many actually. However power is limited by the impedance of headphones and overall they are not going to drive large headphones optimally. Sound quality wise I am consistently impressed. If you have any specific questions let me know.
