I follow the guide, but when I'm about to inject the firmware, I open the file, the program just closes and nothing happens? I've tried with and without all antivirus enabled. Also tried on Windows 10 installation and Windows 11. Same thing happens. Anyone know how I might be able to fix it? Having some issues, for example windows audio doesn't afect audio levels, plus audio starts only after a short delay when doing playback of stuff.

I got one since I needed something with good output power and as Apple dongle etc are plenty good I thought I found the perfect thing. At first I tried with DT880 600ohm to see if it could drive even those and volume was no issue, but the bass was quite messy, but that's fine with such high impedance cans. Then same with Amiron (250ohm). Then finally even with a humble X2(HR) (30ohm). The bass is clearly less clean and punchy. Sub-bass lacks definition and this is in comparison with an Apple dongle (EU version even) which sounds essentially the same as the $10 GraveAudio CX31993 I had here as well. I really can't recommend these for headphone use due to this. I'll try with IEMs later, but considering the output power is not a benefit with them the verdict ought to be essentially the same. Not a good dongle I'm afraid.

Recently got into planar iem's and headphones, got an artti t10 last week but my Abigail can't seem to drive it well(have to push it a bit to get listenable volume) and it sounds different when I compared it to a 7hz 71 which I have on hand(loaner) idk why but the soundstage seems better on the 71(maybe placebo idk).

So, started to search for a good "portable" DAC and stumbled upon this and was gonna order one like 30 mins ago that's when I stumbled upon one of the reviews on reddit talking about the thing being bricked and various other issue's. So my question is that did Fiio fix it or should I pick up something else. FYI I might get an HE400 or Deva pro if they comeback in stock(local vendor).
