Got my Sabaj Da2 yesterday and got it all set up. First of all, WOW this thing is tiny I didn't quite notice it from the pictures but that's not a bad thing at all. It is plug and play; Windows 10 got USB Audio 2.0 drivers for it straight away. These are the options I have with those drivers:
Not going to comment too much on audio since I'll need more time with it but it definitely is a huge improvement over my on-board; drives my Fidelio X2s to insane volume with no distortion and just sounds better overall.
If you look at the packaging in the photo link below and compare it to the ones in
Archimago's review of the SMSL Idea, it's literally all the same but with the branding changed. This unit comes with 3 short cables: full size USB to USB Micro, USB Micro to USB Micro and USB C to USB Micro. So again the same as Idea and they are the same cables. The unit also has the buttons, LED, and ports in the same spot. I would take it apart but I don't have a screwdriver that tiny. Also when I looked at the drivers both
SMSL and
Sabaj offer for these units they are exactly the same as well. I tried installing the XMOS driver and that would give me access to the usual frequencies up to 192000Hz in all the bit up to 32 but no frequencies above. I couldn't be bothered to mess around so I just uninstalled the XMOS driver since I didn't really hear any difference and the Microsoft one is just fine.
Also tried using the Sabaj with my HTC One M8 and it works fine. No random hissing or anything. Seems to deliver the same amount of power as my PC. Tried my X2s and KZ ZS5s with it. Not sure about the battery drain but I this unit for my PC so I probably won't test that.
Here's the rest of the photos including the two above:

So you might as well grab the Sabaj or whatever happens to be cheaper for you
