FIIO K11 Compact Desktop R2R Architecture DAC and Headphone Amplifier (Black)

I purchased this unit as an introduction to the "R2R sound" and yes, it delivers! I was previously using a Schiit Modi+ DAC, and while good as an entry-level DAC, I wanted something different, so I went for this, after seeing and reading several positive reviews.It's an entry-level DAC but it's a very nice unit, well built, feels solid although very lightweight (not ideal for desktop setup if you want it not to move while using the dial or swaping cables); very intuitive to use, no need to read the manual.I'd say it's a very different flavor that my previous Schiit DAC; this one sounds a bit fuller and livelier. Nowadays that I'm using a pricier R2R DAC which has a more refined sound, this one sounds a bit "overproduced"; the sound is truly engaging but it sounds a bit too much "enhanced" specially in the high registers.Don't have too much to say about the headphone output; I didn't use it really. I was using it as a desktop DAC with my home audio system which has a nice headphone amp for late night sessions. I tested back and forth the OS and NOS modes and, while not a night and day difference, the NOS mode makes this DAC a true delight to listen your music through.If you're on a limited budget and want a nice DAC with great sound and that's easy to use, this one is a NO BRAINER!!

The media could not be loaded. I’ve been running the FiiO K11 R2R for a while now, and it’s an incredible way to step into ladder DACs without spending a fortune. Build quality is solid, the display is clear, and it’s truly plug-and-play.Unlike the standard K11, which uses a delta-sigma DAC chip, this version employs a true R-2R resistor ladder to convert digital to analog (No DAC chip). The R2R architecture gives music an organic, textured feel, and makes its OS/NOS switch worth exploring.Here’s how the two modes behave:•Oversampling (OS) is my default. It keeps rock, classical, and movie scores lively and punchy, with tight bass and precise imaging.•Non-Oversampling (NOS) softens edges and smooths the top end — great for older masters like Silver Springs from Fleetwood Mac, bright recordings, or late-night listening sessions.Switching is instant, so you can tailor playback to the recording.My listening chain is: Bluesound Node (coax out) → K11 R2R DAC → Denon AVR-X4500H (analog in) → Emotiva BasX amp → ELAC Debut 2.0 F5.2 towers + dual REL T/1003 10″ sealed subs. I run the AVR in Stereo mode while bypassing Audyssey EQ on the mains — this gives me the transparency of Pure Direct while keeping my subs engaged.Using the Audyssey MultEQ-X PC app, I let it measure the F5.2s’ natural roll-off and it automatically set their crossovers around 40 Hz. I also keep the AVR’s bass management set to LFE + Main, which blends the RELs smoothly with the towers instead of letting the subs “bloom” separately. The result is bass that feels integrated rather than overblown.Price-wise, the K11 R2R is unbeatable. Many R-2R DACs run for about $1,000 or more, but this one is roughly $175. The high-end models may squeeze out another 30–50 % of refinement, yet they’re not 5–6× better — for most setups, that premium price tag just isn’t justified.If you’re curious about R-2R sound and want a DAC that punches way above its price, the K11 R2R is an easy recommendation.In addition, this DAC has made my Sennheiser HD650XX headphones come alive for the first time ever!This DAC is a no-brainer upgrade IMHO, however, based on the reviews you may want to buy the additional extended warranty as this product only comes with a one year warranty.Thank you for reading this and I hope it was helpful!!

Se escucha muy BN desde que lo conecte, 0 interferencias análogas, domina muy bien los stereos y la claridad del sonido, lógicamente hay que usarlos con unos buenos audífonos, en mi caso tengo unos Sony wh1000mx4, le saca el máximo provecho, la luz que emana es muy bonita, pero en mi caso y como se verá en la foto, los mantengo apagados porque me molesta con el tiempo. Conectividad instantánea con Windows. Los recomiendo mucho.

To DAC or not to DAC. I decided to R2R DAC. I’m 60 years old and I’ve become pretty sensitive tocertain high frequency sounds. There is actually a medical definition of it, but I’m too lazy to look it up. I was hoping that this R2R DAC being somewhat analog would tone things down for me, and after two weeks, here are my findings;Wow, the sound stage is enveloping. All the details without the brightness. The bass seems more defined without being too heavy. But the biggest takeaway is that I can now listen to my music at my normal levels ( 40-60db) for hours without having to turn down the volume.It is truly remarkable that this DAC can make my music so much more enjoyable. It’s almost like I’m wearing my very expensive headphones that reveal all the minute details without having to turn up the volume. I am now getting the same effects with my speakers.For reference, my main sources are a Wiim Pro for my hi-res music streaming and a Denon DVD/CD player along with a Audio-technica turntable. My system is powered by a Dayton Audio HTA200.

As someone who is not an Audiophile but just started stepping my toes into getting better audio quality for my set-up I can honestly say this is such a great item it does exactly what it says, it’s also very easy to setup for your personal settings, I like the volume knob and the LCD screen, for the price I say get it, pairs great with both my IEMs and Drop PC38x just takes tinkering getting the right gain but other than that it’s been perfect for the 2 months I’ve had it design is also very nice and sleek and not in the way love it!

I had to watch a few videos on how to make use of it's max power PC settings needed to be tweaked if you buy this make sure you check your audio devices sound settings (Audio Format) example 2 channels, 32 bit, 384000Hz or whatever.
