It doesn't make sense since both of them (older XD05 Bal and newer XD05 Bal 2) have two USB C, one for USB input and one for DC Power.
Edit:
He was talking about the rear power switch, having 3 functions with the Bal2 (Batt, Ext and Charge), now I got that.
"The 4.4 plug enters with a clear resistance and a click at the end.
The function of external, independent mains power has been added"

Is this you're talking about?
I would like to use this little portable dac (and headphone amp) for a while on my desktop PC outputting to my SMSL HO200.
Now, as I'm perfectly aware of the Bal2's line out (aux/line out), 3.5mm, 2vrms and very low THD-N (stated) 0.0008%.
I was wondering if I can get something like 4vrms using...
As I've stated here below this dac has some USB pc oversampling issues (I was wrong about the headphones):

Issues that I have never found before with about...
So, I've just connected to the previous usb port, using the new lime cable. But then I've unplugged the power cord from the dac as there's no more a power on/off switch on the back (Why SMSL?, the DO300EX has one) and then powered it back.
Now the bloody 192 kHz is working on Qobuz like it did...
Yes I have installed the driver, I always install them.
Cable is a good one (should be at least):

Another strange issue I've just noticed right now, if I set the sampling rate to 24 bit/ 48 kHz from Windows /...
Man you're right (although according to a note from the Italian seller these headphones would require 150 - 200h of burn in never high volume lol).
But then what? All I've replace is the headphone.
This way they're working fine though (176.4 kHz):
