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

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.

My Wiim Ultra had an iffy headphone output so I bypassed it with this puppy, using the USB port. My modest headphones sound better than ever! I am very happy with this unit as it also has optical and coax inputs, if needed. It has 3 settings for various types of headphones. The default "medium" setting works great with my headphones so I left it. But it can also work with headphones that need more juice, I guess. Anyway, I am a happy guy!

Excellent quality beyond my expectations
