I am in India too and using G5 with B&O DAC. Great combo with my 64 audio U12
I was truly excited about LG G5 with B&O Hi-Fi Plus (AFD-1200) module during launch. Later I had the chance to audition and found B&O module to provide a definite improvement in G5's audio quality through 3.5 mm audio output.
Internally B&O module ships with the new ESS Sabre ES9028C2M (DAC) with 129 dB SNR, 2 dB improvement over its previous generation ESS Sabre ES9018. We find ES9018 in Vivo X5Max & Lenovo Vibe X3.
The newly released ESS Sabre 9602 headphone amplifier can also be found in this B&O module. The previous ESS Sabre 9601 of X5Max had very good SNR of 122 dB, but severely lacked in amplification department. Hence Vivo in X5Max had to use it as I/V converter and the job of amplification was given to Texas Instruments OPA1612 acting as a headphone amplifier. However with Sabre 9602, ESS was able to dramatically improve the amplification capability while keeping the SNR at 122 dB.
To have a more clear picture below are the audio paths:
Vivo X5Max "HiFi": Snapdragon 615 --> ESS Sabre ES9018-K2M (DAC) --> ESS Sabre ES9601 (I/V conversion) --> TI OPA1612 (Headphone amplifier) --> 3.5mm audio jack
B&O Module (LG G5 ): Snapdragon 820 --> ESS Sabre 9028C2M (DAC) --> ESS Sabre ES9602 (Headphone amplifier) --> 3.5mm audio jack
-------------------------------
Coming to the topic of subjective analysis of LG G5 + B&O module, I used X5Max as the marker. In regards to sound quality I found both to be neutral sounding. ESS dacs are generally neutral sounding, but B&O has a slightly softer tonal behavior of the two. Both produces crisp & clear sounding highs while mids on B&O are less clinical. But where B&O mostly suffered where the lows and repeatedly I felt it lacked the drive to produce that hard hitting & accurately timed lows. X5Max have more driving power of the two, and is more suitable candidate to drive audiophile grade earphones. However you can forget using the big headphones with B&O as my Sennheiser HD 598 sounded anemic at best while with X5Max there was a slight improvement in driving capability.
Nonetheless it was clear to me as both X5Max & B&O are designed to be paired with earphones not big headphones. Better get a Lenovo Vibe X3 if you want real driving capability plus audio quality. In the end of the near three hour audition, I had to give the crown back to X5Max. With B&O you will get equal treatment in mids & highs but lows are where X5Max shine. For example with my Fiio EX1's I can feel X5Max was producing a more accurate & bottomless bass and those 13 mm drivers are really working to produce more thrust. Not so with B&O.
Later one renowned Chinese audiophile website measured & reveled the LG G5 with B&O module is able to produce a maximum output level of - 5 dB, while that of X5Max was higher at -1.4 dB. So now I know X5Max have more driving force than B&O module but nonetheless it was a good try from both LG & B&O.
