Why we love this DAC/Amp

Value for Money

I've found that the best gear isn’t always the most expensive. Some products punch well above their weight and deliver performance that rivals higher-priced alternatives. That’s what we mean with the "Value for Money" badge. It’s our way of telling you that you’re getting something special without breaking the bank. 🥜


These products are all about maximum returns for minimal investment. You’re not just saving money — you’re gaining an audio experience that exceeds expectations. Whether it’s build quality, tuning, or bundled accessories, these picks overdeliver.


When you see '🥜 Value for Money' products, expect impressive performance at an affordable price, making them a smart pick for budget-conscious buyers or first-time audiophiles.
For Budding Enthusiasts

In my experience, discovering good audio gear early on is a bit like tasting great coffee for the first time — once you've had a sip, you're hooked. "For Budding Enthusiasts" is a badge we use for products that are perfect gateways into the audiophile world. They're easy to use, not overly expensive, and give you a real taste of what good sound can be — without needing a degree in audio engineering. 🎧


These are the IEMs, headphones, and DACs that let you dip your toes into premium sound without drowning in choices. They balance performance, price, and practicality beautifully. Whether you're buying your first serious pair or helping someone else start their journey, these picks deliver satisfaction straight out of the box.


When you see '🪴 For Budding Enthusiasts' products, expect simple setups, solid sound quality, and an easy upgrade path — perfect for your first foray into better audio.
Audiophile Community Favourite

When I see a product that keeps coming up in forums, Reddit threads, and community meet-ups, I know it’s earned its place. "Audiophile Community Favourite" is our way of spotlighting the gear that real listeners — not just reviewers — swear by. 🦋


These are products that enjoy a sort of cult following for all the right reasons: consistently great tuning, build, and value. They're the kind of recommendations you'd get from a friend deep in the hobby. If you're the type who likes going with a proven crowd-pleaser, these picks are beloved by thousands of ears.


When you see '🦋 Audiophile Community Favourite' products, expect reliable recommendations backed by passionate users, often refined over years of trust and love from the community.
For Audiophiles at Home

I’ve always loved the ritual of coming home, settling into my favourite chair, and firing up a dedicated setup. Gear labelled For Audiophiles at Home is made for those moments — when you can really sit back and appreciate music in its purest form 🛋️. These products tend to be more powerful, larger, and often require wall power — perfect for a stationary rig.


Here’s the trade-off: these setups often involve external DACs, amps, or full-size headphones, which means more space, more power, but also more immersive listening. They shine when used in quiet environments, where detail, depth, and dynamics can truly be appreciated.


When you see '🏠 For Audiophiles at Home' products, expect: exceptional fidelity, stronger output, and the kind of soundstage that makes you never want to leave your listening chair.
Connect With Cable

In my experience, there’s still nothing like the dependability of a wired connection when it comes to audio 🎧. I love describing it as the direct flight of music — no delays, no turbulence. When a product says “Connect with Cable,” it means you’re getting the most reliable signal path, with zero wireless compression and minimal interference.


Here’s what’s actually happening: a physical cable transmits uncompressed analog or digital signals directly from your source to your gear. This results in lower latency, no signal drops, and consistently better sound — especially when paired with a good DAC or amp. It’s ideal for critical listening, gaming, and professional use. The trade-off? You’re tethered — but for a lot of audiophiles, that’s a small price to pay for sonic purity.


When you see '🔗 Connect With Cable' products, expect: pure, uninterrupted sound quality that lets your gear perform at its full potential — perfect for focused, high-fidelity listening.

Why it Sounds Amazing

DAC Chip

I like to say the DAC chip is the heart of any audio device — it’s the part that actually transforms digital files into music you can hear 🎧. Think of it like a chef decoding a recipe to create a delicious meal. The better the DAC chip, the more faithfully it translates your music. And in my experience, a great DAC can completely change how your headphones sound.


Now, here’s what’s actually happening: a Digital-to-Analog Converter (DAC) takes digital signals (your MP3s, FLACs, or streams) and converts them into an analog waveform your ears can enjoy. Different DAC chips — like those from ESS, AKM, or Cirrus Logic — offer their own sound signatures, levels of clarity, and noise performance. A good DAC ensures accurate timing, minimal distortion, and exceptional resolution.


When you see '⚙️ DAC Chip' products, expect: clean, detailed audio and better synergy with high-quality headphones — perfect for anyone upgrading from average sound to audiophile quality.
Power Output

I like to think of power output in audio gear like engine horsepower, it determines how much muscle your setup really has 💪. Whether you’re trying to drive a pair of power-hungry planar headphones or just want headroom for dynamic peaks, power output is the spec you want to check first.


Technically, it refers to the amount of electrical power (measured in mW or Watts) an amp or DAC/Amp combo can deliver to your headphones. More power means better control, improved dynamics, and the ability to handle demanding gear without distortion. But more isn’t always better, too much power with sensitive IEMs can introduce hiss or harshness.


When you see '🚀 Power Output' products, expect: strong driving capability, better dynamics, and optimal performance with headphones that need serious juice to shine.
Balanced Output

I often say balanced output is like using both hands to carry something heavy — it distributes power evenly and keeps things stable. In audio gear, balanced output helps reduce unwanted noise and interference, especially over longer cables. Think of it as a cleaner, more efficient way to transmit your music, ideal for anyone using high-end DACs, amps, or studio-grade headphones 🎧. You’ll typically find it on gear with XLR or 4.4mm connectors, and it's a must-have if you’re chasing that ultra-clean signal path.


Here’s what’s actually happening: a balanced output uses two separate signals, one inverted, so when interference is picked up along the cable, it gets cancelled out when the signals are recombined. The result? Cleaner audio, better dynamic range, and more power output — especially when paired with balanced headphones. The trade-off? You’ll need gear that supports balanced connections on both ends to really enjoy the benefits.


When you see '⚖️ Balanced Output' products, expect: ultra-low noise, more headroom, and better synergy with high-impedance headphones or sensitive IEMs — ideal for serious listening setups.
Decodes Upto

When I see "Decodes up to" listed in product specs, I think of it like a music translator that speaks more languages than you’ll ever need. It tells you how far a DAC or audio device can go in handling hi-res formats—think PCM, DSD, or MQA—and at what resolution. 🧠🎶


Technically, this refers to the maximum bit depth and sample rate a DAC can process—like 32-bit/768kHz PCM or DSD512. The higher these numbers, the more detailed and lifelike the audio can potentially sound. But remember, real-world improvements depend on the recording quality and your headphones, not just specs alone.

Unbeatable at this price range

Firstly, I decided to go with the non-R2R version mostly because it produces more accurate true to life sound. While some may prefer the warm analog sound signature of the R2R variant, it's not for me.
Secondly, don't forget to change the sound filter to your liking (default is 3). I personally prefer the Minimum Phase Fast Roll-off filter, due to its detailed and clean output.

User picture

Great choice! Love how you’ve tuned it to match your preference for accurate, true-to-life sound. Enjoy the clean, detailed output with your setup!

FIIO K11 - A Gateway to Audiophile Bliss

As someone relatively new to the audiophile world, I didn’t expect a desktop DAC/Amp to completely change how I experience music, but the FiiO K11 did just that. My journey began with some well-regarded IEMs (Simgot Supermix 4) and a HiBy M300 DAP. While they delivered solid audio quality, I quickly realized I’m just not built for IEMs. Discomfort set in within 30–40 minutes of listening. So I pivoted to full-sized headphones, landing on the Hifiman Edition XS after consuming countless reviews and Reddit threads. Initially, they didn’t blow me away, but everything changed after attending an audiophile meet-up in Ahmedabad hosted by HeadphoneZone, where I heard my Edition XS paired with different DAC/Amps. That’s when the penny dropped. Back home, I picked up the FiiO K11 and paired it with my Edition XS and wow, what a difference. I stream via Apple Music Lossless on an M2 MacBook Pro, and while the MacBook’s built-in DAC is good for casual listening, it simply doesn’t do justice to demanding open-back planar headphones. The K11, however, does and then some. The FiiO K11 powers the Edition XS with ease. The sound is clean, detailed, and full of nuance. With a gentle bass boost applied through EQMac, the synergy is just perfect not overpowering, but adding just the right amount of warmth to the already impressive clarity and staging. I’ve been revisiting old favorite tracks, and it feels like hearing them for the first time. Subtle textures, background instruments, spatial effects all of it stands out now. The sound feels alive, expansive, and emotionally engaging in a way my older Sony headphones and AirPods Pros simply never managed. The FiiO K11 has been the most transformative piece of gear in my audio journey so far. If you’re just stepping into the audiophile world and feeling a bit overwhelmed, take your time. Explore, test out different setups, and don’t underestimate what a proper DAC/Amp can do. For me, FiiO K11 + Hifiman Edition XS turned out to be the golden combo — and I couldn’t be happier.

Loved hearing about your journey! The K11 + Edition XS combo sounds magical, cheers to more musical discoveries ahead!

I have been using this desktop dac for almost half a year at this point. It easily drives my sennheiser hd 660s2 and all my iems ( it's kinda overkill for iem lol ) for music/gaming. Setup is easy. Doesn't take much space compared to separate dac and amp setup. Overall good.

Hi there, thank you for taking the time to share your experience with the FiiO K11. Happy listening!

- The volume knob has multiple functions: adjusting volume, powering the K11 on/off, navigating the settings menu, and toggling between line-out/PO.

2. DAC Chip:
- The K11 features the CS43198 DAC chipset, a one of the good DAC chips, suitable for both high and low impedance IEMs and headphones. (Used with the Low impendence IEM simgot supermix 4 on 6.35mm jack power was just right)
- It is compatible with Android, iOS devices, and Windows (note: a firmware update on Windows is essential).

4. Sound Quality
- The bass on the K11 is neutral, with a standard decay, avoiding overly wet or highly musical tones. The K11 maintains a neutral bass without additional emphasis.
- The soundstage offers fine micro-detailing. The imaging and separation of instruments are well-executed, revealing imperfections on poorly recorded tracks.
- It is excellent for gaming due to its soundstage, micro-detailing, and sound retrieval.

Pros:
+ Robust construction
+ Compact and lightweight design
+ Versatile input and output choices
+ Six DAC filter options, attractive LCD display
+ Three gain settings (low, medium, high) with ample power
+ Neutral sound without coloration
+ Refined yet detailed treble, transparent

Cons:
- there are issues with the firmware and drivers on Windows. I had to locate the latest firmware on a random Fiio forum instead of directly downloading it from the product page it was annoying

-The high output impedance of the balanced output may not be compatible with low-impedance IEMs such as the SIMGOT Supermix 4 that I own. This is not necessarily a disadvantage, as it is typical for low-impedance IEMs.

In the Box:
- A 6.35mm to 3.5mm adapter
- One USB-A to USB-C cable
- A power plug (DC 12V 2A)

IEMs Used:
1) SIMGOT Supermix 4
2) 7Hz Legato
3) KZ ZS10 Pro

Tested Music Players:
- foobar2000, Tidal, and Apple Music

Games Tested:
- Helldivers 2, Atomic Heart, Elden Ring,The Witcher 3, call of duty and many more

Conclusion

the K11 has impressive price-to-performance ratio. In terms of sound quality, it delivers a transparent and neutral output, and the power output is remarkably high for its price point. Most DAC/amps in this price bracket tend to offer lower power output and fewer features.
it is an amazing buy at this price point.

Budget King Desktop DAC AMP from Fiio

First, Thank you Headphone zone for another excellent service and prompt delivery.

My trusty desktop DAC Amp, Xduoo XD05 Plus, finally given up after over 5 years of extensive use and I was looking for a replacement. I opted for the K11 because of its better performance to price ratio and high power output at 300 ohm compared to the iFi Zen DAC V3.

The Fiio K11's Sound quality is impressive for the price. It's a clean, neutral DAC Amp with no frequency bias. The biggest surprise is the expansive sound stage, providing a holographic presentation. The imaging is accurate. I love the AKM sound signature of the Xduoo XD05 plus compared to the Cirrus DAC chips in K11, the Xduoo XD05 is more musical sounding to my ears. But the K11 offers better background noise, wider sound stage and better imaging, better separation of instruments, and far better channel balance with 6.3 mm connection, which was a big issue with my Xduoo XD05.

Comparing it to the dongle DAC Moondrop Moonriver 2 Ti (which has the same Cirrus DAC chip x 2), the bass goes little bit more deeper and textured with Moonriver 2 Ti than the K11. The Moonriver 2 Ti has slightly better resolution and its able to pull out more details from good quality high resolution audio files. On the other hand, the K11 has wider sound stage and holographic sound presentation.

The K11's minimalist form factor bend seamlessly with my desktop setup. The operation of the K11 is very simplistic, though I wish it had a ON/OFF switch instead of holding down the volume knob.

Overall, I am satisfied with my Fiio products, from my first Fiio BTR5 to Fiio Q3 to Fiio K11. I would love to try out the ultimate Fiio K19 or Topping DX9 someday.

Thank you for taking the time to leave such a detailed and positive review for the Fiio K11. We are glad to hear that it has exceeded your expectations and that you are satisfied with its performance and features.
