Good sound quality, more output power or nice design?

All we need is a dual CS43131 in class AB, with 4.4mm output, with 30/60 steps hardware volume button independant of the host (for ear safety btw), with filters selection and detachable usb cable !

My video about KA13. Great cost-effective device even for desktop usage

Been reading reviews on Amazon that mention a bug where a volume button press results in max volume. I'm hoping to hear some updates or fixes on this.

Dear friend,

This problem has been fixed in latest v0.11 firmware. Thanks for your attention.

Best regards

With the KA3 which Gain and Impedance setting should I use to get close to Line-out as possible for a PC? I'm guessing High/High?

Dear friend,

You could try to set impedance to high and gain to low.

Best regards

Since reviews don't mention it, let me: KA13 catches interference from mobile networks.
And it's on a severe side, had to cease using it on the go. Still use it at home, but mobile operations were delegated to Penon Tail, which is almost silent in this regard.
Shielding needs improvement, Fiio.

What are some example scenarios where you hear the interference? I have only used mine at home so far but I'm interested to put this to the test.

Most notable when phone switches/loses network, e.g. entering an elevator, or going underground.

Dear friend,

Which device are you connecting the KA13 to? And you are playing on-line or local music at that time?

Best regards

How come fiio doesn’t have MQA support ?

Pixel 5, mostly offline music, sometimes online streams.

MQA will die soon anyway, no need for supporting it.
I am Tidal User aswell but really don't care for it at all
I prefer cheaper hardware instead because in the end the customer needs to pay the MQA license fee

@FiiO I would like to know the reason to choose op-amp behind KA13. Why do you decide to pick up SGM brand over Ricore RT6863? Moreover, Why don't you use SGM8261 (which has higher specs) than SGM8262?

I just ordered one from ali. Such a good price over Amazon. I need a bit more power and hope this does the trick. My Hiby FC4 is decent but not quite enough power on some music.
