My first interest is how many W per channel does it have on SE & BAL & maybe the most important question is how many units will come with the AKM chip ? As far as price goes I'll take my guess and say it's around 650 USD

 

[Ra97oR]

Does it come with a remote volume control?

 

[ahmonge]

Is the volume knob surrunded by colour light to indicate the sampling frequency?

Hi,
1,The SE output power should be greater than 1.5w, the balanced output power we are trying to debug, we hope to bring you better data.
2,Because of the shortage of AKM chips, there will only one in the K9Pro.

 

[FiiO Willson]

Does it come with a remote volume control?

No, It will not come with a remote control, but it has an APP, just like our other products

 

[FiiO Willson]

Is the volume knob surrunded by colour light to indicate the sampling frequency?

Yes, different sampling frequencies and MQA etc. are displayed in different colours

In K5 pro volume knob backlight is too bright especially when listen at night.

The K9 Pro will have an indicator light switch in the APP, so you can choose to turn it off if you feel the light is too bright
This may be more friendly

is it noise free for ultra sensitive IEMs? high low gain?
Can it be used as Dac only?(volume is bypassed)

The noise we are debugging, it is more difficult but I think it will be perfect in the end.

Of course the K9 Pro can be used as a standalone DAC, which is a must

What will be the main difference between AKM4499 and Dual ESS versions?
I'm thinking for sound quality, power, noise, not technical differences.

Dual ESS versions hasn't started yet.
But there are definitely functional differences,Probably cheaper in price.

I can't tell you exactly now because there are many variable things.

When and will there be measurements (thd+n, snr, imd, frequency response divation, channel matching, crosstalk ect)?
