No updates, did not change any settings. I also checked on the Samsung s22 and Samsung S21 Plus, iPhone 14pro the same result. I think it's the device's defect.

My problem was more a random static sound than a clicking sound, so it may not be the same problem, but it's close enough that it's worth mentioning, and it's easy to check. Either make sure there are no nearby cell phones, or they are in "Airplane Mode." In normal operating mode, cell phones have no adverse effect on dongle DAC/Amps sound, but occasionally when they switch towers, communicate with towers for maintenance, or search for towers in weak zones, a cell phone broadcasts at higher power and different frequencies that can cause interference with audio devices. Further, the better-sounding cables use better materials that make better "antennas" and are often less shielded, resulting in picking up static you can hear. Also, some DAC/Amps devices are better shielded than others. For example, FiiOs are better shielded than Earmen, in my experience. Again, it was very intermittent and infrequent since normal operations of the cell phone did not cause it, so it was very hard to track down, and I thought for sure it was a defective device, cable, or connector. I had a similar problem with a Verizon cell phone booster on my desk that was affecting my Focal Active Near-Fields Monitors. Good luck!

Dear friends,

Check the following picture to get the comparisons of our KA series products~

 

[BSV2007]

But what about sound comparison to iBasso DC04Pro?

But what about sound comparison to iBasso DC04Pro?

Most dongles sound the same, there is no real audible difference.
I've compared this to the Moondrop Dawn, E1DA 9038 and they all sound the same.

This conclusion is very subjective. For me all dongles has different sound. And sometimes the differences are quite significant.

I'm just shocked how happy I am with what came out of FiiO. I really liked the KA5, for me it's better than Quloos MC01 and Cayin RU6.
so far, I use it with a PC + foobar2000 (WASAPI Exclusive, there is no point in ASIO in this case). soon I will get an iBasso CB18, and the union will be perfect.
Well, FiiO, I didn't expect to be very pleased, although the last KA3 was also beautiful. I expect in August new KA7. just a little bit and you can bury the DAP price 700$)))
I recommend to familiarize yourself with the product. reading reviews is not something, everyone will have their own opinion.
to describe the sound is not a grateful thing, everyone should listen to it himself, for me the difference is in one word in resolution, it is above all praise from KA5. the detail is perfect.

Could you describe please the difference of sound compared to the Cayin RU6?

 

[jjxaker]

Could you describe please the difference of sound compared to the Cayin RU6?

RU6 catches a lot of noise from 4G traffic, changes the volume with interruptions (there is no such thing in DAP with R2R), low frequencies are not enough, the sound is sluggish in some styles and can be said to be very correct, this does not allow you to enjoy all styles of music. that is, RU6 is not universal.
When using KA5, all these negative aspects are absent. but at the same time, the advantages of RU6 are preserved, such as: high detail, wide stage, high frequencies are soft, moderately light feed.
But keep in mind, this is my personal opinion. with different headphones and in different conditions, users' opinions may change. for example, I have not tested it with a style of music such as heavy metal, I do not listen to this, but I suspect that dark headphones will be needed, ka5 light dongl.

One of the most important attribute of a good dongle is good EMI shielding, which historically FiiO has done very well. I agree.

 

[northixora]

I have M15 and KA5., but I always want to listen to the KA5.

 

[Fourier transformer]

maybe a firmware with a 30 volume steps option would satisfies everyone's need, especially for the 3.5mm output

 

[jjxaker]

I have M15 and KA5., but I always want to listen to the KA5.

and note that KA5 is so much smaller than Questyle M15. and the KA5 is lighter, apparently they used thinner aluminum and that's good. it's amazing how FiiO managed to make such a good and cheap dongle.
I was not even interested in listening to my M11 Plus ESS, the difference is not so obvious... KA5 even sounds more widely. I'm suspecting that these new op-amps are doing all this wow effect. I have never seen or heard anything about SGMICRO before, as I understand it, KA5 is the first product with these chips.
The MCU controller is almost not visible in the photo, I suspect that the STC Micro STC8G2K64S4

 

[Billyak]

I normally don't comment on DACs in general because they do sound so similar imo. I have used a multitude of DACs & DAC/amps but the KA5 is one that I am impressed with. From a completely subjective point of view I find the KA5 to have a very very natural sound with great timbre. I don't know how else to describe it and even though my brain tells me this is all placebo I am enjoying it none the less.

Haha, you are so professional
