Recently, we got a unique product to test. Currently, there are only two models of keyboards with a built-in DAC and headphone amplifier in the world, and one of them is the Fiio KB3. We will talk about it today.

This keyboard has several unique features, and we want to figure out who it is for, how it sounds, and whether it is worth the money. Given its uniqueness, let's start with an analysis of the features and sound.

## Feature Overview

It is important to define the methodology for comparison and identification of key points for Fiio KB3, given its niche. Let's start with the fact that two Cirrus Logic CS43131 DACs and two SGM8262 operational amplifiers are installed inside the device.

The Cirrus Logic CS43131 DACs in the Fiio KB3 are known for their ability to provide clear and detailed sound, which is especially important when listening to high-resolution music. These DACs, typically used in high-end portable audio devices, are used here to improve sound quality directly at your workplace. And the SGM8262 operational amplifiers help to minimize distortion and noise, providing a richer and more emotional sound, making each listened composition more alive and realistic.

## Sound Analysis

The starting point in our comparison will be a quick test of the MacBook Pro, which already has a decent built-in DAC. Headphones worth about 2,000 euros were chosen as headphones to avoid sound limitations and at the same time to check the efficiency of the amplifier.

We created [a playlist on Qobuz](https://open.qobuz.com/playlist/19379861) that includes tracks that we believe are suitable for testing this keyboard. The playlist features various genres, but we consciously did not focus on jazz and classical music, as we assume that KB3 is aimed at a slightly different audience.

During a quick test of the MacBook Pro DAC with the tracks "Blinding Lights" and "Crew Love", it was noticed that, despite the good bass in "Blinding Lights", the sound seems a bit closed. "Crew Love" demonstrates the purity of the sound, but there is a lack of spaciousness and resolution. In general, the sound through the MacBook Pro is clear, but not as detailed and rich as we would like.

Now we move on to the most exciting stage: we connect the headphones to the 3.5mm jack of the Fiio KB3. Conveniently, no additional drivers are required. We listened to the same and other tracks:

- **The Dark Knight, Hans Zimmer**: There is a noticeable improvement in resolution, although the bass seems a bit restrained.
- **Hotel California, Eagles**: The sound becomes more natural and full, with good transmission of nuances.
- **Blinding Lights, The Weeknd**: The bass has improved significantly. Even at maximum volume, the sound is not tiring, maintaining its dynamics and development.
- **Crew Love, Drake**: Good clarity and nuance, great separation of voices.
- **Enter Sandman, Metallica**: Excellent drums that create a sense of closeness.
- **Moth to a Flame, Swedish House Mafia**: While listening, we unknowingly turned up the volume to maximum - the sound is captivating, without any complaints.

The use of two Cirrus Logic CS43131 DACs in the Fiio KB3 keyboard significantly improves the soundstage, making it more spacious and detailed. This is especially noticeable when listening to complex musical compositions, where each instrument and voice sounds clear and separate. Thanks to this, the use of the Fiio KB3 keyboard turns ordinary listening to music into a deeper and more immersive experience.

The amplifier in the Fiio KB3 really proved to be powerful and effective, doing an excellent job of maintaining sound quality even at maximum volume. This is an important aspect for any audio device, especially when it comes to listening to music through high-end headphones.

## Functionality

Sound control on the Fiio KB3 is significantly more convenient and enjoyable than the standard volume control on the keyboard. This is ensured by the built-in volume knob, which allows you to accurately and easily adjust the volume level. Additionally, the keyboard is equipped with two USB ports, which expands its functionality, allowing you to connect additional devices, such as a mouse or flash drive, directly to the keyboard, which is convenient and practical, especially with a limited number of free ports on the computer.

In addition, the Fiio KB3 is equipped with mechanical keys with Gateron G Pro 3.0 yellow switches, providing pleasant tactile sensations when typing. RGB backlighting adds aesthetic appeal and provides customization options, which will be valuable for users who want to give their workspace a personal touch. And the compact 75% design makes the keyboard ideal for saving space on your desktop.

## Appearance and Packaging

The outer packaging of the Fiio KB3 looks presentable and modern, decorated with the company's slogan "Born for Music". The keyboard comes with a long enough USB cable for connection, as well as a simple instruction manual. It is worth noting the absence of a specialized cable for connecting to Mac devices, which will require the use of an adapter. However, overall, the first impression of the keyboard was very positive, and there was an immediate desire to connect it and evaluate its sound.

## Verdict

The Fiio KB3 is an excellent purchase at an affordable price. For 110+ euros, you get not only a gaming keyboard, but also a built-in DAC and headphone amplifier. This is a great offer for those looking for a solution to improve sound quality without adding external devices. The Fiio KB3 is ideal for optimizing your workspace and reducing the number of cables, while it is not only attractive for audiophiles, but also enriches the gaming experience for gamers, improving the sound of dialogues and special effects.

Explore Sennheiser's latest offerings at CES 2024, showcasing a trio of new audio products set to redefine the listening experience.


In the world of high-fidelity audio, the union of an amplifier and a speaker system is akin to a carefully choreographed dance. Each component, mastering its own role, seeks to complement the other—ultimately culminating in an experience that transcends mere sound into the realm of sonic artistry. While a plethora of articles, debates, and tech talks have muddied the waters around the topic of amplifier power versus speaker capabilities, it's crucial to cut through the noise for a nuanced understanding. Let's unpack this complicated relationship for audiophiles and casual listeners alike, making the narrative universally accessible but richly detailed.

## The Endless Debate: Power Dynamics in Amplifier-Speaker Pairing

The first thing to grasp is that there are two prevailing ideologies in this arena:

1.  **Amplifier Power > Speaker Power**: Advocates for this approach argue that an amplifier with greater power than the speaker can handle offers better audio quality.
    
2.  **Speaker Power > Amplifier Power**: The counterargument suggests that having speakers that can withstand more power than the amplifier can produce offers a safety net for the speakers.
    

### The High-Powered Amplifier Approach: The Dynamics and Dangers

**Pros**:

-   **Extended Dynamic Range**: The added power reserve lets your amplifier gracefully manage the ebbs and flows of musical dynamics. Imagine listening to a classical piece; the pizzicato strings would remain crisp, and the fortissimo climax would hit you without distorting.
    
-   **Reduced Clipping**: A more potent amplifier seldom pushes its boundaries, reducing the odds of hitting the dreaded "clipping" stage, which can cause permanent speaker damage.
    

**Cons**:

-   **The Peril of Overpower**: If an amplifier sends an overpowering signal, it could cook the voice coils of your speaker, causing irreparable damage.
    
-   **Budget Concerns**: High-wattage amplifiers can become a monetary black hole, especially if you aren't planning to use the added power.
    

### The Speaker-Heavy Equation: The Cautions and Cost-Effectiveness

**Pros**:

-   **Speaker Longevity**: If your amplifier cannot produce power exceeding your speakers' capabilities, the risk of damaging the speakers diminishes.
    
-   **Economical**: Generally, less powerful amplifiers are lighter on the wallet, an attractive option for budget-conscious listeners.
    

**Cons**:

-   **Clipping Risks**: Lower-wattage amplifiers risk clipping when pushed, leading to distortion—a mortal enemy to both speakers and audiophile sensibilities.
    
-   **Volume Constraints**: If you're hosting an outdoor party or have a large listening space, a lower-wattage system might not cut it.
    

## Time to Damage: A Red Alert for Audiophiles

It's not just the theoretical risk that should worry you; real-world damage can happen quicker than you think. An overdriven amplifier can cause distortion, and even brief exposure to such unclean signals can wear down your speakers. So, the golden rule? Turn down the volume at the first sign of audio discomfort.

## Beyond Wattage: Sensitivity and Impedance

In audio, wattage is just the tip of the iceberg.

-   **Sensitivity**: Expressed in dB/W/m, this metric indicates how loud a speaker will sound for a given power input. Hence, a high-sensitivity speaker powered by a low-wattage amplifier could potentially outperform a low-sensitivity, high-wattage counterpart.
    
-   **Impedance**: Given in ohms, impedance essentially tells you how much electrical resistance a speaker offers. Misaligned impedance between the amp and speakers can result in energy waste and possible damage.
    

## Universal Accessibility: The Amplifier in the Modern Age

Here's the kicker: Modern amplifiers, built with precision engineering, are generally forgiving. They are designed to operate efficiently, providing a consistent power curve that makes it easier for users globally to set up systems without an advanced engineering degree.

## Conclusion: A Balanced Harmony

The dialogue between amplifier power and speaker capabilities is indeed complex, but it's not unapproachable. By understanding these various elements, you're not just making an informed choice; you're making a statement about the quality of sonic experience you desire. Whether you're listening to music in a tiny apartment or setting up a home theater, the key is to find that sweet spot where your amplifier and speakers dance in perfect harmony.
