Sorry if this has been asked, I have been googling and not found any particulur answers, the audio on the z3 is too low, I have very easy to drive headphones and several others and it is just too low (Dunu 2000j, Hifiman re600s, Senn ie80)
Tried the mods, but the sound sligthly distorted and it seems that editing the file is the best option, as sony sets a super low limit, apparantly.
Sooo, I know I need to edit :
<ctl name="HPHL Volume" value="19" />
<ctl name="HPHR Volume" value="19" />
<ctl name="RX1 Digital Volume" value="84" />
<ctl name="RX2 Digital Volume" value="84" />
But what is the diff? im getting the impression "HPHL Volume" is amp, and rx1/2 is just digital amplicfication.
So what is the difference and what do they do?
