The birth of the FIIO K series and its worldwide popularity has led to a continuous investment in desktop products, and the FIIO HiFi desktop system is our latest exploration. Now, we have a new understanding of entry-level desktop DAC and headphone amplifiers.

With a full range of audio outputs, robust output power, and convenient functions, the K11 offers a more cost-effective and comprehensive performance than any other product in its class. What’s more, the slim body with minimalist design will also become one of your desktop HiFi companions.

A more comprehensive entry-level DAC/Amp

On the K11 are USB, optical and coaxial inputs as well as 4.4mm, 6.35mm, RCA line-out, and coaxial outputs. Having more inputs and outputs than other typical entry-level amps means the K11 is more than capable of meeting your needs of putting together a capable audio setup; under a 32Ω load, the max undistorted output power under balanced output goes up to 1400mW, allowing it to easily drive many kinds of earphones and headphones.

Moreover, within the K11 lies a specially-designed audio circuit designed for great sound quality. This is backed by more than 16 low-noise LDOs for precise voltage stabilization and powered by an external 12V switching power supply.

Reassuring user experience seen in design details

As a comprehensive entry-level desktop amplifier, the K11 delivers on all fronts at the level of the listening experience and user experience.

The K11 has 3 separate gain levels, each gain level having its own volume curve. This allows the K11 to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder to drive over-ear headphones.

In addition, its use in USB DAC mode does not require a driver on Windows 10 and above systems, and can also be used with video game consoles such as the PS5 and the Switch. Simply plug and play for worry-free usage whether you are enjoying music or being immersed in games.

A minimalist aesthetic design

With a complete set of audio outputs and professional audio architecture, the K11 still maintains a slim build. Its aluminum alloy body features a durable Hi-Res VA display for a quick and clear grasp of the current working state. The multi-function volume knob not only helps to fast control different functions, but also to appropriately connect to different headphones or audio setups.

Under the concept of the minimalist design, the K11 is also considered to provide another visual effect on your desktop. For one thing, it is available in two colors at the same time, Obsidian black and Midnight silver, to help create a personal style of desktop. For another, it combines the RGB ambient light into the FIIO LOGO, which allows a quick glance at different sampling rates, as well as making the color, light pattern, and brightness all adjustable.

Looks really nice! Double press to switch outputs seems like a good solution for desktop use. I hope theres not too much funtionality in the multiknob. I will wait for reviews, but I am absolutly considering this. Hope it works nicely with Linux too.

@winnipegaudioenjoyer according to the quick start guide, the line out is adjustable.

Will the signal go to headphones and line out simultaneously or will there be a need to select output ?

Is this higher or lower in the product stack than the K7? I have the K7 but if this is a bit better I'll buy it.

It is lower than K7. here is the relastionship of our headphone amp.

K5PRO--- K11
K7-------- K13
K9---------K15
K9PRO----K17

K11 is the first upgrade model in our line up. I think we may upgrade K7 in 2025 and it is still very popuar now cause it has more power output and better sample rate supports.

I'm looking forward to the K13. I love my K7. For $200ish USD the K7 sounds better than some $500 dac/amp solutions I've heard from other brands.
Is there any chance Fiio would consider putting not just a 6.3 and a 4.4 but also a 2.5mm output on the future dac/amp units? I don't know if it would be possible or affordable for Fiio to do that, but it would really open up a lot more possibilities and reduce my need to use adapters.

You will be better off changing your cables to 4,4mm.

2,5mm is being phased out, even from small dongles and DAPs.

Fair enough but I still have 2.5mm stuff. The Fidelio X3 from example by phillips. It has a 2.5mm balanced cable and buying replacement cables for it is crazy hard because it has a weird termination going on at the headphone end. Also I've got a lot of 2.5mm cables for IEMs due to having a dongle for my phone with 2.5mm out. I would just prefer to not have to use any adapters. Eve if 2.5 is being phased out, I'm still going to have all this 2.5 stuff. Backwards compatibility is always a good feature with any tech product IMO.

I can understand your situaiton but we have decided remove 2.5mm headphones jack from our products 1 yeare ago, cause the 2.5mm connector is not as solid as other connector.
