FIIO K11 Desktop 1400W Power Balanced Headphone DAC & Amplifier 384kHz/24Bit DSD256 for Home Audio/PC 6.35mm/4.4mm/RCA/Coaxial/Optical (Black)

I am running as a DAC/headphone amplifier for a Bluesound streamer via the optical connector. I have a pair of Audeze LCD-2 headphones which are tough to drive and for which I have upgraded to a 4.4mm balanced cable. The FIIO K11 drives the big Audezes with ease and the combination sounds great - detailed with clear, deep bass, clear midrange and nice high frequency definition without sounding shrill or sibilant. The menus are very easy to navigate - I migrated from a Chord Mojo2 which was a nightmare with all its coloured LEDs (it eventually died and I have not got round to getting it fixed yet). I am very happy with the FIIO K11 and would recommend it strongly. For the price it is an absolute steal!

I'm using the FiiO K11 to power my HIFIMAN Ananda Nano, it gets loud and very clear. The RGB FiiO logo adds a touch of luxury.

Using it as DAC to connect tablet,chromecast audio,arylic s50 pro plus in and out to behringer fb800 with marantz sr7500 the result is amazing. The clarity and separation is perfect.

Le FIIO K11 est une vraie réussite ! Ce DAC/ampli offre un son clair, puissant et précis, avec une excellente dynamique. La prise en charge du DSD256 et du 384 kHz/24 bits permet de redécouvrir ses morceaux préférés avec un niveau de détail impressionnant. Les multiples sorties (6,35 mm, 4,4 mm, RCA, coaxial, optique) rendent ce petit boîtier ultra polyvalent, parfait pour un usage sur PC, Mac ou système audio domestique. La puissance de sortie est largement suffisante pour driver des casques exigeants. La finition noire est sobre et élégante, et la prise en main est simple, même pour les non-initiés. Rapport qualité-prix imbattable dans cette gamme ! Je recommande chaudement aux audiophiles comme aux utilisateurs en quête de meilleur son au bureau

This FiiO K11 works great .after a little time setting it up ( which is easy ) I have it connected directly to a Sony 5 disc cd changer via optical cables . I plugged in my Beyerdynamic dt 770 pro X headphones and WOW everything is crystal clear , getting everything my cds have to offer ! And if your into lighting you can make it change colors and it can be set to rotate through all the colors as you listen to you music . And if your like me you can shut all the light show off and leave one color on or black the lights out and the front screen can be turn of as well ! It also comes with a electrical 3 prong connection thats not shown it the pictures !

The FiiO K11 punches way above its price and size. It delivers a clean, powerful sound with enough headroom to drive most headphones comfortably, especially through the balanced output. The tuning is neutral and detailed without being harsh, making it a great match for both planars and dynamics. Build quality feels solid and premium. The volume knob is smooth, the screen is bright, and the menu is simple to navigate. It stays cool during long sessions and doesn’t clutter the desk. USB connectivity is stable, and switching between inputs is quick. For everyday listening, gaming, or music production, the K11 offers excellent clarity and separation. You get high‑resolution support up to 384kHz/24‑bit and DSD256, which is more than enough for most libraries. If you want a compact desktop DAC/amp that delivers clean power, great usability, and impressive sound for the money, the K11 is an easy recommendation.

Good, high quality. Sound it more powerful and punchy. Doesn't take up too much room, good settings for the onboard RGB as well! Good weight, suitable for a desk. Good value for money and very easy to setup, albeit poor instructions.

Perfect for my hd560s
