iBasso DX260 Review

iBasso’s latest mid-range digital audio player (DAP), the DX260, has arrived as the successor to the highly praised and award-winning DX240. Unlike its predecessors, the DX260 no longer supports the modular amp-card system, meaning you cannot customize the sound signature by swapping amplifier modules. However, iBasso has introduced a new feature in the DX260 – an easily removable back cover that provides full access to the battery. This allows users to effortlessly replace the battery themselves, simplifying the process.

Technical highlights

The iBasso DX260 stands out as the pioneer in the world of Digital Audio Players (DAP) by incorporating an innovative octa-DAC chip matrix. This groundbreaking design utilizes eight CS43198 flagship DAC chips, with four chips dedicated to each channel, resulting in exceptional performance and unmatched measurements.

iBasso’s FPGA-Master has undergone extensive algorithm development and now enters its second generation, known as 2.0. Serving as the audio system controller, it plays a crucial role in reproducing signals and maintaining signal integrity. By directly requesting audio data from the SoC (System on a Chip), it ensures a seamless and synchronized audio experience. This is achieved through the utilization of two NDK femtosecond oscillators, which generate and synchronize all audio clocks, providing a fully synchronized single clock source.

Furthermore, the DX260 has a dedicated USB receiver, specifically designed for USB DAC mode. This feature offers low latency and supports ASIO/WASAPI, enhancing the overall audio performance. The device supports high-resolution audio formats up to 768kHz/32bit PCM and native DSD256.

The FIR filter

The FPGA-Master 2.0 allows for further exploration and development of the potential of the 8pcs CS43198. The DX260 is equipped with a synchronous parallel output mode that minimizes “discrete distortion” between DACs, enhancing overall performance. It enables precise control and adjustment of the DAC clock and data at a picosecond level, allowing for independent adjustment of each DAC data stream. By utilizing the “delay parallel” of 4 DACs, a hardware analog FIR filter is created, which helps in averaging the differences between multiple DACs, reducing distortion, and enhancing sound details and realism effectively. Users can choose to turn off the FIR filter or enable it in 2x or 4x sampling modes.

Design and layout

The previous iBasso DAPs, including the DX240 and DX320, featured a chassis with sleek, curved corners and rounded edges. In contrast, the DX260 boasts a fresh, angular design accented by asymmetrical lines, sharper corners, and more defined edges. This combination creates an industrial and more aggressive design. Despite its lightweight and compact size, which allows it to fit comfortably in the palm of your hand and be easily operated with one hand, the sharp corners may feel slightly piercing. However, to address this concern, the DX260 comes with a silicone case included as a standard accessory.

The design is sleek and simplistic, with the characteristic iBasso multifunctional wheel and playback control buttons located on the right side of the DX260. Despite appearing delicate, the wheel is quite sturdy due to its deep shaft within the chassis, ensuring durability. The rotation may not be as smooth initially, requiring some time to break in.

Located at the top of the device are the 3.5mm SPDIF jack, USB 3.1 type-C port, and a micro-SD card slot without a dust cover. The bottom features the 3.5mm single-ended and 4.4mm balanced headphone outputs, which can also function as line level outputs with fixed or variable levels.

Crafted from a single block of machined aluminium, the chassis boasts a top-notch finish and assembly. It’s worth mentioning that the back cover is reinforced with hardened glass.

Operation and user experience

The DX260 runs on a Snapdragon 660 SoC paired with 4GB of RAM and 64GB of ROM, delivering a smooth user experience. It operates swiftly and responsively across various applications, with no signs of lagging. The 5-inch touch panel allows easy one-handed use, showing excellent visibility and vibrant colors. Streaming services such as Tidal and Qobuz perform efficiently, allowing seamless internet browsing and multitasking without any interruptions.

Moreover, the DX260 features USB and Bluetooth DAC functionality, along with the capability to output digital streams via USB or digital coaxial, making it suitable for use as a transport to an external DAC.

Dual OS system

Just like all iBasso players, the DX260 includes a dual operating system that allows users to select either a customized Android 11 OS or iBasso’s own Mango OS for a high-quality and pure listening experience. The Android 11 OS includes the official Google Play Store pre-installed, making it simple to download preferred applications. Additionally, users will have access to familiar Android features such as the drop-down menu and various customization options.

The Mango OS

The Mango OS prioritizes superior sound quality by eliminating non-essential tasks. It restricts the use of streaming services, permitting only local playback from the SD card and USB DAC mode. Additionally, the Mango OS features powerful graphic and parametric equalizers. You can expect swift database access speeds and quick build times, even when using high-capacity SD cards.

Battery duration

The battery has a capacity of 4400mAh and supports fast charging, allowing for a full charge in approximately 2.5 hours. iBasso states an average playtime of 14 hours, which may be slightly optimistic, however, the actual duration proved to be quite satisfactory. When using the player with its balanced output, in the low gain setting, streaming high-resolution content, I was able to enjoy 10 hours of continuous use. Furthermore, it is possible to charge and use the device simultaneously, although there is no desktop mode available that bypasses the battery.

Replacing the battery

The user can easily replace the battery due to the removable back cover. Simply utilize a torx screwdriver to unscrew the two screws that secure the metallic part holding the back cover. Afterward, cautiously remove the back cover, ensuring not to damage it, and gain complete access to the battery. The replacement process is straightforward and does not require any soldering.

Accessories

The bundle consists of a silicone protective cover, a USB type-C cable, a 3.5mm to RCA coaxial (SPDIF) cable, the renowned iBasso burn-in cable, and documentation. An optional premium leather case can be purchased individually for $59.

Power output and associated gear

The DX260’s balanced output can deliver a maximum power output of 6Vrms or 1015mWpc/32Ω, while the 3.5mm jack provides 3Vrms, 280mWpc/32Ω. Although it may not be the most powerful DAP in its category, it still possesses enough power to drive a wide range of headphones, including the iBasso SR3, HIFIMAN Arya Organic, Sennheiser HD660S2, and Meze Liric 2, which were used for the review.

In terms of background noise, the device is virtually silent, making it suitable for use with even the most sensitive earphones such as the iBasso 3T-154, FiiO FX15, and Soundz Avant.

All headphone and earphone cables used are from Lavricables. Following standard practice, the iBasso DX260 underwent over 100 hours of continuous music playback and was updated to the latest 2.02 firmware.

Listening impressions

To put it simply, the iBasso DX260 stands out as the most transparent and neutral player I have ever had the opportunity to test. While all iBasso DAPs are known for their linearity and neutrality, the DX260 has managed to surpass them all, as well as most other players in the market. It’s worth noting that there are indeed other DAPs that are neutrally tuned and transparent, and I can think of quite a few of them, however, iBasso has taken neutrality, fidelity, and transparency to new heights with the DX260. What sets it apart even further is its ability to maintain its transparency and neutrality without any digital glare or artificial treble. The DX260 is truly unique, offering masterclass fidelity and precision without sounding sterile or clinical. This is a remarkable achievement from iBasso that is sure to be appreciated by many.

Upon using the iBasso DX260, rest assured that you are truly experiencing the sound characteristics of your headphones and the source material’s quality rather than the player itself. While some may feel let down by the unavailability of swapping amp cards as seen in other iBasso DAPs, the DX260 caters to purists. It is designed for individuals who require assurance of possessing the most transparent and linear-sounding DAP that ensures reference technicalities without any additional sound alterations.

It is essential to highlight once more that the DX260 offers exceptional clarity and transparency, which does not translate to a dull or boring listening experience. Unlike a sterile measuring device or a clinical monitoring tool, the DX260 delivers a musical and immersive sound with rich overtones, colorful harmonies, and lifelike timbre, making the sound produced by the DX260 truly exceptional.

The technical specifications are top-notch and can only be compared to high-end DAPs. The bass is rich, prolonged, with outstanding precision, remarkable clarity, and an incredibly impressive layering that surpasses expectations. Challenge the iBasso DX260 with your most intricate and demanding audio files, and it will excel effortlessly. Without any difficulty, it reproduces the subtlest details and even the quietest notes while maintaining an astonishing dynamic range and impactful sound. The textures may not be overly robust or intense, but they are perfectly balanced, not too thin or dry either.

The mid-range exhibits exceptional clarity and refinement, surpassing its competitors yet again in terms of resolution, precision, and fluidity. The sound quality is remarkably natural and lifelike, while maintaining a neutral sonic signature that neither leans towards warmth nor coldness. The treble is vibrant and lively, extending exceptionally well and radiating light. The DX260 portrays a swift and nimble performance, far from being a laid-back and relaxed player. It does have a slightly bright character, but rest assured that it does not produce any harsh or piercing sounds. However, it is worth noting that this player may not be forgiving towards low-quality recordings, especially when paired with headphones that have a bright or analytical sound signature.

And more…

The DX260 shines with a remarkable refinement, with textures that are exceptionally smooth and free of any roughness. Detail retrieval is outstanding, allowing even the faintest notes to be heard against a background of absolute silence. Every sound within the recording is vividly captured. Despite its precision, the player’s presentation is far from analytical or monotonous. Rather, it expertly weaves together all the details to create a complete and lifelike musical experience.

The DX260’s separation and imaging capabilities are truly exceptional, setting a new standard in its class. I have yet to come across another player that can surpass it in these aspects. Not only can you distinguish the sound of each instrument, regardless of their number, but you can also clearly perceive the precise positioning of the performers during the recording. While headphones typically don’t replicate the experience of speakers, the DX260 has the ability to deceive you into thinking you’re listening to a high-quality 2-channel system. Moreover, the soundstage is remarkably expanded and holographic, creating an immersive and grandiose auditory experience with a stunning sense of ambiance. In fact, the DX260 can even transform soundstage-shy headphones like the Sennheiser HD660S2, making them sound more open and spacious than you could ever imagine.

Further sound tweaks

Choosing the 2x and 4x sampling options on the FIR filter will improve the clarity, separation, and imaging of the sound. However, you may notice a slightly sterile and dry sound compared to having the filter deactivated. The DX260 operates optimally with the Mango OS, providing a slightly better transparency and fidelity than the Android OS. These features, along with the five digital filters, allow for precise adjustments to match the player’s sound signature with different headphones and music genres.

Vs the FiiO M15S

The FiiO M15S, priced at $999, features a larger 5.5” display and a higher capacity 6200mAh battery. However, the screen is of lower resolution and not as vibrant as that of the DX260. The M15S is bulkier and heavier compared to the iBasso DX260, making it less pocket-friendly. The M15S has a bit more power at 1200mW/32Ω and includes a desktop mode that bypasses the battery, a feature absent in the DX260. On the other hand you can’t replace the battery as you can do with the DX260. Both devices utilize the same SoC and 4GB of RAM, but the iBasso DX260 operates on Android 11 while the M15S runs on Android 10.

In terms of sound signature, the FiiO M15S delivers a fuller, more impactful bass, albeit lacking the same level of definition and layering found in the DX260. The M15S offers a warmer, more colorful sound compared to the DX260, but falls short in terms of transparency and neutrality. While the M15S provides thicker textures and a slightly larger soundstage, it cannot match the separation and imaging capabilities of the DX260. The M15S stands out as the least digital-sounding FiiO DAP, offering a remarkably natural timbre. On the other hand, the DX260 excels in delivering a more refined and resolving treble, also free from any digital glare.

Vs the iBasso DX240

The iBasso DX260 features the same SoC and memory setup as its previous model, with an upgrade from Android 9 to 11 resulting in a faster and more responsive user experience. The screen of the DX260 has been enhanced to be brighter, more vibrant, and colorful. One significant change is the absence of the interchangeable amp-card system, replaced instead with a user-replaceable battery.

The DX240 with the stock AMP1 MK3 offers a similar sound performance to the DX260 in terms of neutrality, fidelity, and transparency. However, the DX260 surpasses the DX240 in every aspect. It provides better clarity, definition, transparency, precision, refinement, and resolution. The DX240 falls a bit short in comparison when it comes to separation, imaging, immersion, and holography. One significant distinction is that the DX240 has a little more clinical and sterile timbre, along with some digital glare and artificiality, unlike the DX260. Additionally, the treble of the DX240 is a touch sharper and brighter, lacking the natural and realistic sound found in the DX260.

However, switching to the AMP8 MK2 from the stock amp card will result in a warmer and more organic sound on the DX240. The timbre will sound more natural and analog-like, while reducing digital glare. Still, the DX260 remains the more neutral and transparent player with superior technicalities and enhanced resolution. Some users though may still prefer the DX240/AMP8 MK2 for its warmer and more relaxed sound signature, or for the option to swap amp cards for added versatility.

In the end

The iBasso DX260 stands out as an exceptional player, thanks for its unparalleled transparency and neutrality that surpass even flagship models from iBasso and other brands. It delivers top-notch fidelity and precision while maintaining a musical and engaging sound that avoids artificiality and sterility. Remarkably, iBasso has achieved a flagship-level DAP at a price point below $1K, making the price to performance ratio truly remarkable. With innovative features hidden within its compact body, the DX260 is also the first player in its class to offer a user-friendly, replaceable battery.

The DX260 is now my go-to DAP for assessing headphones, as well as being a top pick for music listening pleasure. It is the ideal option for those looking for utmost clarity and accuracy without compromising on musicality and involvement. iBasso has truly excelled with the DX260, setting a high standard for themselves to exceed in their upcoming releases – a task easier said than done. Nevertheless, I remain optimistic that iBasso will continue to impress us with even more remarkable products in the coming days.
