Unique for the price!

Usually i never write a reviews, but BubisUK.... are you kidding??? does not go very loud and I do not use high impedance headphones???
I think you made mistake not increasing volume in application or windows mixer. This thing have A LOT of power as it have +/- 9V supply and discrette transistor output. Overall architecture of that thing is normally provided on 200 USD devices for home use.

However, issue is: very glitchy amanero - it can work only with Nvidia USB-C port. On Intel chipset's USB I have problem with Sound starts to noticebly changed after about 4 mins of playback (very strange). Also USB-C ports are hot hold the cable like my phone or laptop. SO portable use is not possible, because cable all the time is disconnecting. Also, sometimes device go to deepsleep and I cannot wake it up after, just replug the USB cable.

Wish Zishan do not stop and better performance with next device!

I found how to fix problem rebooting on watching youtube


2 sound chipset driver seems crash while on youtube (it crashed soon as I paused and wait 3sec, )

I solved that step,

There is basic PC sound chipset , you need to set it as 'default'
then watching youtube , PC chipset works with speaker .
and when I listen music on foobar2000 , It works with Zishan U1 on earpohones,
It's a half soulution but if someone having same problem it would help the situation.

It sounds better than PC sound chipset

I am testing this on PC , and I installed driver from here - https://amanero.com/drivers/setupuac2.exe
but 1st time I played with MusicBee , PC has been crashed serveral times when I click preference on MusicBee music player,

I changed Foobar2000 , It works fine with WASAPI
and You better check and change on Windows - Sounds - preference - make highest sample rate and exvlusive mode allow,
(for me It's 24bit , 192000Hz )

I haven't tested with phone yet, It seems I need to use spceific player like UAPP or Hiby in order to use USBC output.

Sounds more clearer and fuller than my basic PC sound chipset wihch is reaktek ,
If I use Musicbee again it sould be great but well
So I am fine so far unless it crashes or has problem . heh

My Pc rebooting on and off while using this DAC

I have tested just 1 hour but I get rebooting ,

I instralled driver from here - https://amanero.com/drivers/setupuac2.exe

It seems unstable yet.

Only buy this if you want problems

Very bad device. Does not work with any of my 3 phones (and I know they support audio DAC's). There are people that have issues connecting this to their PC's even.
Soundwise it is alright but it does not go very loud and I do not use high impedance headphones.
Build quality is ok only the volume knob is not the best - there is quite a big range on it that you have to turn untill you hear anything.
There are better dacs out there, so better skip on this one.
