Yeap
PS: isn't that an XLR in the picture anyway??? He could have converted to 2.5mm :| I'm confused.
Is the 3.5mm a TRRS version ?
the 2.5mm/3.5mm is indeed a trrs version.

So this is not good to use :That makes sense... at least it should be clear to readers that this isn't your run of the mill 3.5mm TRS jack that is used. It may give people the wrong idea of trying 2.5mm TRRS to 3.5mm TRS adapters and secretly get away with it somewhow.
So this is not good to use :
3.5 Balance TRRS is rare, it seems that only hifiman & ibasso is in usethe 2.5mm/3.5mm is indeed a trrs version.
What is holding you back putting a small battery in the case too? If it can solve this problem by acting as a buffer, it would be worthwhile I thinkHi, I working on 3.5mm jack DAC #9038D(and 9038S gen 2 as well) DAC in the same case where the soft-start issue solved. It may smoothly start with Android or iOS device without external power but.. due to quite high output power, my iPad Air2 switching off its USB power as soon I increase player's volume. My Android behaves even worse, it can reset itself in case if its USB consumption too much. Hence, the problem with an external power source is not solvable principal, without Li-battery inside of DAC. Yesterday I googled for "USB DAC requires camera adapter" and the first what was found is dragonfly cobalt! Even such a tiny power DAC requires the Y-splitter(that the "camera adapter" is but from Apple and 10x more expensive). What we can expect from 10-20x more powerful 9038S/D? BTW, I prepared the additional operating mode for 9038D/S_gen2 called "IEM" mode, when the output power will be limited at -15dbfs for safe operation with insane low IEMs up to 4ohm(200mW@4ohm THD<.0015%).
LH Labs uses it as well but I don't even know if they're in business anymore. Still rare though.

I call powerdac bullshit. Signal is signal, if the sound is different, there must be some measurements that are worse on one of them. As tested, 9038S is way better performer. There are other tests like imd, multitone which are not tested on powerdac But it suspect the "detail" is just high frequency distortions. Null test may also show the cumulative errors.What kind of sound difference do you get between this and poweramp V2? I would be driving a planar headphone which is not hard to drive.
Alright thanks I will get 9038 thenI call powerdac bullshit. Signal is signal, if the sound is different, there must be some measurements that are worse on one of them.

sorry IVX
Well yeah but if the amp can take more power the power output (max) should be higher too.The powerdac has a mode where the signal is 'f-ed up' on purpose. In that mode you get substantial 2nd harmonics added on purpose.
Also, when using the app you have 'basic tone control' functionality.
That will work with any USB source and program. Most software players have their own tone control though.
Another feature is 'loudness control' (not loudness war setting) but varying bass levels depending on volume setting.
The 'added value' is in the added 2nd harm. distortion IF you prefer that alteration of the sound.
It also has 7 PEQ filters so you can correct a headphone (when you know how to do this)
9038 is much smaller in size though.
IVX seems to prefer the distortion mode. Not possible in the 9038 though.
Powerdac can also be set to 'performance mode' in which case it is like the 9038.
Do note that PowerDAC and the early 9038 models require extra power to start with certain phones. The newer revision has a slow start.
USB3 won't deliver more power in the headphones as it is dictated by the power supply voltage and headphone impedance.
So your choice may have to depend on functionality here.
