Sampling Rate And Bit Depth

Ever wonder how those ones and zeros on your computer magically transform into the rich melodies that fill your room?


The secret lies in a tiny device called a Digital-to-Analog Converter (DAC). Think of it as a translator, taking the digital code of your music and meticulously sculpting it back into a smooth, analog wave that your speakers can understand. But just like a sculptor needs the right tools, achieving audio nirvana with a DAC depends on two key factors: sampling rate and bit depth.


Sampling Rate:

Imagine your favourite song as a complex rollercoaster track. The sampling rate refers to how often the DAC takes measurements of this digital track, measured in kHz (kilohertz) or thousands of times per second. A higher sampling rate, like 96 kHz, is like taking a ton of pictures of the track, capturing every twist and turn with incredible detail. Lower rates, like the standard 44.1 kHz used in CDs, are like taking snapshots at a theme park – fun, but you might miss some of the subtler details that make the ride truly exhilarating.


Bit Depth:

Now, think about the sculptor's tools. Bit depth refers to the precision of each measurement the DAC takes. Imagine the number of colours available to the sculptor. With higher bit depth (e.g., 24 bits compared to 16 bits), each measurement can capture a wider range of values. This allows the DAC to recreate subtler variations in the sound wave, resulting in richer and more nuanced audio. It's like having a broader colour palette for building a more detailed and lifelike sculpture of the sound.

THARUNKUMAR P (Ludhiana)
One of the best budget desktop DAC&Amp for Music and gaming.

1. Design:
- The K11 is compact and portable for a desktop DAC, easily fitting in a bag.
- It boasts an aluminum alloy body, imparting a sense of sturdiness and longevity.
- The front panel features a 6.3mm and 4.4mm port, a display, and a multifunctional rotary knob.
- 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, acclaimed for its high-fidelity conversion of digital audio signals into analog, suitable for both high and low impedance IEMs and headphones.
- This leads to a cleaner and more precise sound output.

3. Connectivity:
- The K11 connects to source devices (such as phones, laptops, etc.) via USB-C.
- 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 yet delivers a firm punch and impact, 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.

-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, and The Witcher 3

Conclusion

After several weeks of testing, it's clear that the K11 boasts an 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 and fewer features. The K11, however, checks many boxes with its range of features and excellent sonic performance for both music and Games. It stands out as a highly recommendable product that offers great value without breaking the bank.

Thank you for your detailed and thoughtful review!

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.

Great little Bunny 🐰

So far I was more into using some high-end mobile devices for listening music and This is my first time I thought to use a dedicated DAC/AMP for headphones. To my surprise this little wonder from Fiio have performed beyond my expectations. It has kickass soundstage, excellent flat response and mind blowing power. Wish it had auto power down feature when not in use. But other than that K11 works flawless for your needs.

Hey there,

This makes us really happy and we really appreciate the genuine feedback! Your review will definitely help fellow audiophiles to make an informed decision.

Opens up tunes unheard earlier in tracks. Far better than small form factor dongle form dacs

Sharing my review after 18 days of usage. Tested with Beyerdynamics Dt 880 Edition, AKG k275, Sony WH-H910n (via wired Aux cable) in Medium Gain & USB input mode. Beyer & akg took sounded better ,not as neutralish as quoted in some reviews. Bass is prominent with mid bass clarity & optimum sub bass presence. Flawlessly handled 192k PCM coded Flac files. Bass thumpyness also has satisfactory presence. USP being the Top part illuminated RGB pulsating/static Fiio Logo.
Being mostly metal head & hyperpop listener, worked fine. Intrument sounds which I heard for the first time after plugging beyer dt 880 ed cans to Fiio k11 was absent earlier even after playing LP flac files using my Dell Alienware inbuilt Realtek & Nahimic sound engine. Regarding Youtube & gaming working fine but dunno who's gonna spend 12k for enhancing sound quality for playing games & streaming youtube.
I was earlier worried regarding authenticity of device or whether refurbished, but that all was answered since Fiio devices comes with scratch card pasted on the device box with 20 digit code that can be verified over the Fiio Website.

Well what's the best part is the device works super fine with Samsung phones (used S22 Ultra) for testing with usb c to c male cable that comes with 45Watt samsung charger. While upon my enquiry headphonezone support did tell me theres shear possibility that it will work with samsung s series device so opt out of choosing fiio k11 if to be used with aforesaid as DAC. Also, Saw some reviewers sharing review that volume boost control not working with windows, i tested myself with windows k11 works fine but do have to installing Fiio USB DAC Driver Fiio_v5.58.0 erstwhile if one ends up installing Fiio_v4.47.0_2018-08-03 it will not show up Fiio K11. Sound quality is good I can tell that since I use multiple cans such as Buds 2 Pro, Sony WF1000xm3, Sony WH-H910n, Beyerdynamics dt 880 pro, Akg k275.
Regarding sound Signature k11 is more or less has a darkish flavour that works best with metal tracks.

Able to drive DSD 128 (.dsf) file smoothly without any hiss or hiccups on S22 Ultra in HiBy Music player app with DSD mode selected Native in HiBy Music setting.

Hey there,

This makes us really happy and we really appreciate the genuine feedback! Your review will definitely help fellow audiophiles to make an informed decision.

Vikash K (Hyderabad)
K11 is one of the best neutral budget dac, amp

Absolutely happy with the performance of the product, there are a few glitches with the software but I am expecting them to be ironed out soon. Tested the single ended output with HD 650, HD 300 pro, HD 569, MDR 7506, SHP 9600, source was Apple hi res Lossless and lossless via iPad through usb c and lg Oled tv with optical input.
I am impressed by the quality and neutral sound of this product.
Power output is enough to drive the HD 650, would love to try the balanced output once I get the balanced cable. Got an ifi 3.5 mm to 4.4 mm to use the balanced output but unfortunately it has the exact same volume as the single ended output, maybe it’s a product limitation.
Please make sure you use this with a high quality audio source otherwise you will not be able to realise their potential.

Hey Vikash, thank you so much for the amazing feedback! It means a lot to us. We are so happy to hear that you are loving our products and services.
