We also found this difficult to understand during the design of the product.

But after a long time of our efforts, we were never able to achieve a satisfactory result, so we finally gave up.

When playing some DSD512 or 768k tracks, there will be problems, so we blocked this function

Ahh thanks for the explanation. Please consider to release a firmware that disable MQA so that we can get the DSD512/768k playback.

Yes, that would be great. MQA is snake oil anyway.

if they would use xmos 216 they won't have that issue with MQA and DSD512, but they went for the cheap solution xmos208, is not bad, but now they have these issues..

Hello, support for DSD512 and Xmos chip is not related, is to stand in the whole system to consider and make the decision

Xmos208 is not cheap. And we will not use Xmos216, we are currently working with MQA to evaluate the possibility of Xmos316 supporting MQA

No such plan at the moment

Is it mentioned anywhere what the differential is between low, med, and high gain levels are?

como se desempeña con el LCD-2 ?? Si lo logra mover? Cual k9 tienes el akm o ess .?

Tengo la versión AKM y la he estado escuchando regularmente con el LCD 2 Cerrado. Para mí, el sonido es excepcional y combina muy bien.

FiiO website Desktop Amps Faqs has the descriptions listed here.

Thank You.

@FiiO Willson or @FiiO - What could explain the fact that I can successfully stream dsf/dff (DSD) files natively in JRiver on my Mac? My K9Pro plays these files, and displays the green LED ring indicator, suggesting the DSD files are streaming natively. Does the green indicator LED truly represent DSD native streaming, or is this some sort of compromised version of DSD streaming within Mac/JRiver? I can successfully switch to DoP mode in JRiver, and observe the Yellow indicator LED (>48kHz) during playback, and switch back to DSD bitstreaming mode and observe the Green indicator LED (DSD). I'm happy in any case, just curious about what exactly qualifies the LED color changes, and the fact that I'm able to stream DSD on my Mac, when theoretically it "shouldn't" be possible...

Dear friend,
I tried the Jriver but not sure whether the same version one. It seems that after setting DOP in Jriver, all the files are output in DSD instead:

Sorry I am not quite familar with this app as well. You could also try the A+ app?

Best regards

The story of Dual 9038Pro value-for-money all-in-one DAC/Amp FiiO K9 Pro

Chapter 3 New use scenarios | New territory, FiiO embarks on a new journey from the K9 Pro

In this chapter, let's talk about FiiO's next product focus: desk HiFi series products.

We all know that FiiO has always been paying much attention to various portable amps, portable music players, in-ear monitors, etc. It can be said that the K9 Pro is the first product in our history that is truly designed for audiophiles and suitable for desktop use scenarios. Therefore, we have also done some research and investigations on this market. Thanks to everyone's help, we have also made some conclusions based on the previous market feedback of our K5 Pro and other products. Any suggestions will be appreciated. Just leave us a message below.

No matter living in a mansion, a dorm in the university, or renting a room, we all have our own small world which is usually a desk.

The core of the desk is the computer host + keyboard + display screen, or a laptop. Generally speaking, except for collective dormitories, we will basically be equipped with speakers and headphones. Therefore, various inputs and outputs of the device should be as complete as possible.

With water glass, school supplies and other stuff, usually the space of the desk would be nervous. Therefore, what we need is a compact device with excellent sound performance and easy operation. (otherwise, we can just use our computers.)

The K9 Pro is exactly the one designed for such a use scenario and needs. Let's make a conclusion.

(1) The K9 Pro is kind of a compact one among all-in-one DAC/Amps with a built-in linear transformer. When designing it, we carefully considered the needs of putting it in both horizontal and vertical manners. As a result, the K9 Pro is not too wide (takes less space when placed horizontally) or too thin (for stable placement when placed vertically). It is relatively rare for desktop all-in-one DAC/Amps with such width and height.

(2) When designing the K9 Pro, we have considered the access needs of wireless (via Bluetooth) and wired connections (via optical, coaxial, USB, Type-C), so it can be easily connected to various common devices such as mobile phones, notebooks, computers, digital audio streamers, etc.

Meanwhile, it is equipped with RCA LO, XLR BAL LO, optical/coaxial digital out, 6.3mm SE and XLR BAL headphone outs. Basically, it can meet your needs for using in-ear monitors, HiFi speakers, and other headphones.

(3) Considering that many users need to switch between speakers and headphones frequently, we have designed a convenient output mode selection switch, which is convenient for users to switch output devices at any time without plugging and unplugging headphones or speakers. Considering that many of our users have both earbuds and headphones at hand, we have designed 3 gain levels of Low, Medium and High, which are more friendly to both high sensitivity/low impedance headphones.

(4) Finally, a reasonable price decides if a product will be highly accepted in the market. To be honest, the market capacity of desktop DAC/Amps is not optimistic according to the research. There are more brands and models in the market due to its low technical demands. Plus delivery expense and other reasons, manufacturers would generally put margin before sales volume. However, we FiiO are a freshman in the desktop market, and have our own pricing principles. The two versions of the K9 Pro have very high cost performance and very high configuration, and you can make a comparison to other DAC/Amps with two 9038PRO DACs on the market.

Hi there,
Looking at the specs it seems the 9038pro chips have some advantages over the 4499. Do you think that overall it's a much bigger upgrade in sound and technicalities or just a different flavor?

In fact, there is an improvement in technology and indicators, but it is very small.

The sound has its own characteristics

Without being able to test both, could you briefly describe the sound characteristics of the 4499 vs 9038Pro?
