I think you may have an issue with your source material or else your headphones - All I did was I set several of the RX1 and RX2 entries in the mixer_paths.xml file to the settings shown below and wow, it sounds fantastic with volume maxed! - Now to reiterate, when you are that close to the clipping level of the internal small amp, there is no tolerance for any crap, such as the following:
● mp3 files
● mp3 320 files
● aac files
● other lossy crap files
● in-ear headphones
● Beats headphones
● other junky headphones
and it is not even enough that your files are a lossless format such as FLAC, WAV, or AIFF - you also need to ensure that the songs were ripped correctly with good equipment using
Exact Audio Copy (EAC)
if your headphones were not built by one of the following companies, there is a good chance that you need to rethink your choice of brand:
(alphabetized by country where the firm is headquartered)
Austria:
● AKG
Germany:
● Beyerdynamic
● Sennheiser
● Ultrasone
Japan:
● Audio-Technica
● Denon
● Fostex
● Sony
● Stax
USA:
● Audeze
● Grado
China:
● HifiMAN
I am using:
all FLAC files ripped with EAC
Fostex T50 mk3 headphones with ZMF cowhide pads
Jet Audio player - no equalization
As far as the built in speaker on the back of the phone, it is not designed to play any louder than it does stock, so trying to increase the volume of it, is silly.
my settings:
line number within the mixer_paths.xml file is shown first
Code:

30 = <ctl name="RX2 Digital Volume" value="91" />

2483 = <ctl name="RX1 Digital Volume" value="91" />
2484 = <ctl name="RX2 Digital Volume" value="91" />
and so on.....
