Found this measurement of balanced out K7:
1664641740-BAL-THDN-Ratio-vs-Measured-Level.jpg


Interesting it looks way powerful than the advertised spec. I wonder why is that ?
32 ohm 4W at 1%
68 ohm 2.5W at 1%
300 ohm 600mW

What is the gain of low/high btw ?

Dear friend,

That's because the parameter in our website shows the output power for long time stable working mode.
Switching the gain to "high" increases the volume and power output and is suitable for high impedance or low sensitivity headphones; "low" gain is suitable for low impedance and high sensitivity earphones.

Best regards

Interesting. When is it gonna be available ? What is the price ? Is knob position visible in the dark ? Circular light doesn't seem to hit there.

Any plans for K7 Pro ? K7 is a nice product but i feel there is a spot in your line up between K9 and K7 needs to be saturated. More powerful and maybe class A amp section or with a screen to show volume. I like the decision there is no MQA or bluetooth. These features unnecessarily rise the prices.

Dear friend,

1. If everything goes well, the K7 will be available in oversea market at about next month.
2. No, but you could judge the volume level by hearing the sound instead.
3. There may not be K7 Pro. The successor for K7 may have different name. We will report your feedback to the engineer as well.

Best regards

A new baseline for balanced desktop sound! Desktop DAC and Amplifier K7 Is Officially Released!​

6868916.jpg

Since the K5 Pro has become a hit on the market, we have enlarged our investment in desktop DAC and amplifiers. The K9 Pro was a great proof which was also very popular among users. However, between these two products, a further-level DAC/Amp is still absent. This time, the K7 is checking in to be the new baseline for balanced desktop sound in the FiiO family!

The K7 follows the same audio architecture as in the previous high-end K9 Pro, a truly balanced circuit consisting of DAC + LPF + Volume control + Buffer amplifier + Pre-amplification + Headphones. Audio signals from each channel are processed by the fully differential audio architecture.

As for the amplifier, the K7 applies the THX AAA 788+ that was designed for desktop devices. Under a 300Ω load at 1% distortion of each channel, it is capable of outputting 560mW, and 2000mW into a 32Ω load at 1% distortion of each channel. As for the DAC, its left and right channels are each equipped with AKM's latest AK4493SEQ DAC chip, for classic high quality and warm sound. As for the USB decoding chip, the XMOS XUF208 featured in the K7 uses dual clock management to handle various music formats with ease.

The K7 features a power design consisting of multiple independent stages, with the voltage of each stage being regulated by low-noise LDOs. Feeding this power design is an external 12V switching power supply. All in all, the K7's power design is designed to supply plentiful, clean power for an extraordinary listening experience. To ensure that the K7 always operates at its best, the overheating, overloading and DC protection systems are here to lead you to an immersive and wonderful listening experience.

In addition, the K7 features an all-aluminum alloy construction, carefully finished with CNC and other processes. Its petite design only measures 55mm thick. Coupling with the brilliant RGB light show fits perfectly on modern desks.

Key features of the K7 include:
-- Truly balanced headphone amp

-- Multiple intelligent protection systems
-- Power supply with numerous independent LDOs
-- Included 12V/24W low-noise switching power supply

Fresh out of the box. Surprised me how big this thing is. I know it was gonna be larger than the smaller K3 2021 shown on top. But ya this thing is a serious desktop dac amp. Played some music and played some games out of my laptop. The sound of this thing is serious business.

I am actually very surprised how good this thing sounds for the bucks. $200 and this thing sounds nothing like what you would expect a $200 dac/amp might sound like. I own players that cost over 10X the cost of this thing and I dont feel this thing is lagging behind for SQ. So far so good. I have been using the K3 shown above the K7 for ease of use on my laptop as that thing punches above its price point. The K7 however is playing on a completely different league.

I will be testing my headphones and earphones on this for my eventual review but for now. I am smitten by the sound of this thing. I didn't know what to expect from the K7 but my goodness this thing sound awesome. It is easily comparable to my IFI signature it is playing at that level. Will make sure this thing gets a good work out before posting any more impressions about it. But for now if you guys were curious about it. The sound quality is outrageous for the bucks. It is a no frills powerful dac/amp that can do both IEMs and headphone and drive them with aplomb. Every single Fiio item I had a chance to evaluate this year has been a surprise. None more than this thing right here. I will be testing this out the best I can by simply using it every day on my work/gaming laptop. So far....... Thing is the bomb! Love it.

Aliexpress link returns a 404.
Dear friend,

Sorry our Aliexpress store doesn't support the shipment to Germany. But the distributor in Germany would have the K7 in stock some time later. :)

Best regards
