When is it coming to UK? I've asked both advancedmp3players and otic audio and they keep saying 'maybe next week' :slight_frown:

Try plugging into a different computer to test. Try UAC 1.0 just to see if it's a compatibility problem. If it still has problems, then it's faulty, send it back for replacement.

Go back to the K11. Spending 5-10x on more expensive amps isn't necessarily going to bring the joy back.

How is the H2 just for bluetooth LDAC? Is it better than the BTR7? I do like the wheels and large buttons

OK, I think I have narrowed down the problem. If there is sound already playing (youtube, music, games, etc) when I turn it on, then it will not get past the USB IN screen and will be completely unresponsive. I have repeated the test several times, and it happens 100% of the time so far...

Still bugged with a different USB C cable. Is FIIO looking into this, considering many people have this problem?

It just happened again, twice now in a week. I'm going to try a different USB C cable and will report back if it happens again. If it continues to bug out with a different cable, I'll have to return it :slight_frown: EDIT: FYI, I'm plugging straight into my desktop motherboard, no adapters.

I also had this problem today, except unplugging and pluggin back in didn't fix it. I had to unplug both the power and the usb cable, then turn it back on, then plug the USB in again. Are you using the the USB cable that came with the K11?

Great recommendation! I bought them based on your post (and the first youtube review I could find), also they are very cheap. I have had the Ultrasone Signature Pure for a few days. Very good build quality, the face plate on the earcups feels and looks very premium. My head is not so big and...

Well, so far here are some of my thoughts: The unit has a good weight to it, I thought it might be too light on the desk, but it stays put. The rubber base helps a lot to keep it stable. The power cable is a little short. The first section from the plug to the transformer is 18 inches, the...

Just picked up the K11, hope its good!

I would also like the firmware.

I just blasted the full 200+mw of the KA11 into my 10ohm IEMs :slight_frown: Luckily I wasn't wearing them at the time, but I hope they are not damaged. My fault really, I plugged them into a new device for the first time and forgot to adjust the volume beforehand. Just a tip so you don't forget 👍

Well I have both and I'm impressed, the KA11 actually sounds quite a bit better than the DC03pro. Considering the KA11 is less than half the price and I only bought the DC03Pro a year ago, what an improvement a year makes! Lighter/smaller/cheaper/more power, the KA11 is pretty good. No hardware...

I'll have both later today, I'll come back with impressions/opinions.
