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

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

Ich hab den FiiO K11 ursprünglich nur als Upgrade für meinen SteelSeries GameDAC 2 geholt – und was soll ich sagen: Mission erfüllt, Overkill aktiviert. 😎 Nutze ihn an meiner PS5 Pro, und er wurde direkt erkannt, sofern man den UAC 1.0 Modus aktiviert (kleiner Tipp für alle, die sich wundern, warum nix passiert). Klanglich? Top! Endlich genug Headroom für meine anspruchsvolleren Kopfhörer wie den Arya Organic oder den Meze 109 Pro – der GameDAC 2 kam da einfach nicht mehr mit. Was gefällt besonders? Klang: Klar, kraftvoll, detailliert – perfekt für Gaming UND Musik. Anschlüsse: 3.5 mm & 4.4 mm – flexibel wie ein Yoga-Meister. Menü: Super simpel, kein unnötiger Schnickschnack. Filter 2: Mein persönlicher Favorit fürs Gaming – schön ausgewogen. RGB: Wenn man's mag, ein nettes Gimmick. Wenn nicht, einfach ignorieren. Fazit: Der K11 hat meinen alten DAC in Rente geschickt und liefert richtig ab – besonders für den Preis. Wer auf der PS5 (oder generell) mehr Power für seine Kopfhörer braucht, bekommt hier ein echtes Kraftpaket mit Stil zu einem vernünftigen Preis.

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.

I wanted to get into higher end audio, namely by finding a desktop DAC with balanced audio output. For under $150, this was an incredibly sensible purchase for my needs. Unit itself is made of solid material, sleek black finish that isn't a total fingerprint magnet, with full size audio out as well as the aforementioned 4.4mm balanced out. My headphones ROAR out of that balanced out, even on low amplification! Love the aesthetics from the LED lighting on top, which I didn't even realize was a feature when I plugged it in! Pairs great with a room and setup full of RGB. If you want to get into upper mid to higher end audio, this is a fantastic starting point that'll run out of any desktop or laptop, or even game console with no drivers needed! Drivers are necessary for ASIO out on desktops though, which can be tricky to install. Overall though, great value and sound, these make your headphones even better.

Before forming your opinion, change the default digital filter from 3 to 6. Where 6 is no oversampling and has less harshness compared to 3 which made sibilance more noticeable. Some have stated filters 1 or 2 are also better sounding but 3 is the worst for me. Power, resolution and features are great for the price. I had been using Chord Mojo (1st iteration) fed by HiBy R5 and Sennheiser HD560s, but the Mojo is bettered by this. Not yet tried the balanced output. Small, stylish and easy to operate. Must run off mains power with supplied adapter but I prefer this.
