A while ago, we took a closer look at the K9 Pro ESS and were quite impressed with its performance. Today, FiiO has introduced a new product called the K11, positioned as a budget offering of the K series, and in this article, we are taking a closer look at it. 

Packaging and Accessories

The FiiO K11 arrives in a well-designed package, carefully compartmentalized with foam to protect its contents. The attention to detail in packaging ensures the DAC’s safety and adds to the unboxing appeal. Inside the box, the K11 is accompanied by a set of essential accessories. These include a power cable and a power adapter for connecting and powering the device, a USB cable for linking it to a digital source, an 6.35mm jack adapter, a quick start guide for easy setup instructions, and a warranty card.

Design and Build Quality

The FiiO K11 sports a sleek and modern design that marries functionality with aesthetics. Its chassis resembles the Apple Mac Mini computer. The device’s chassis, available in an Obsidian black or Midnight silver finish, is constructed from a sturdy aluminum alloy, giving it both a premium feel and durability. Its compact dimensions ensure that it won’t dominate your desk space.

The front panel of the K11 consists of a custom LCD screen featuring high brightness levels and clarity. It is a monochrome display designed to be always on without suffering from burn-in, ensuring that key playback information remains visible at a glance without compromising the screen’s longevity. Accompanying the display is a multi-function volume knob that doubles as a tactile and intuitive interface for volume control and menu navigation.

Flipping the K11 reveals a well-thought-out back panel for the price, housing a variety of inputs and outputs, including USB, optical, and coaxial, alongside 4.4mm, 6.35mm, and RCA jacks. This assortment of connections makes K11 ready to pair with a broad array of sources, from consoles to phones and computers. The details extend to practical considerations as well; the big and wide silicone anti-slip pad ensures the device stays firmly in place, while the adjustable RGB logo lighting on the top adds a customizable visual appeal or can be configured to provide visual feedback on the audio format being played.

The overall impression is one of a device that has been crafted not just to look good but to withstand the rigors of extensive use. Also, the DAC can be used vertically, which is useful if you have limited available space on your desk.

    All I am looking for is a mp3 type juke box to put all my favourite tracks on that can act as a hi fi attachment and a headphone player too. But to be affordable for most hi fi lovers.

    Some people complain that on some heavy bass notes or loud sounds in movies the amp cuts the output to prevent clipping I guess (suggested track for testing this is Retronik by Swing bit). Second, a lack of a remote prevents this device to be used both as a DAC for a speaker system and a headamp. Getting up to adjust the volume every time is not convenient. Looking at the inputs and outputs it is designed also for this use case but a lack of a remote holds it back. Ideally if you add a remote and a solid BT Implementation the price would go up close to 200 range where you are confronted with strong competition like the topping dx3 pro plus with more power, lower distortion a remote and a solid BT Implementation. Also people say that windows volume control does not work via USB , only via optical which could be a deal breaker for some. Solid product but definitely not without cons even at this price point…
