Customer Reviews

Based on 5 reviews
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.

Shipping FAQ

Which countries do you ship to?

We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.

We cannot ship to addresses that are "PO boxes or APO/FPO".

*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.

How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*. 

*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.

Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.

Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes. No refund will be processed for such cases.

Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.

For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments. 
Please contact us before placing an order, should you have any queries regarding shipping.  

How long does it take to receive the order after it is placed?

For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products. 

Customized items will take a longer time. Please contact our staff for more information.

On normal non-sale days, once your parcel has been shipped out:

  • For Standard Shipping, it takes about 2-4 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country, its customs and other factors.* The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to Express Shipping or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.

*Note: Timings might be affected due to festive seasons or other unforeseen circumstances
