iBasso DX340 debuts as a flagship digital audio player, including a Titanium Limited Edition of just 300 CNC-machined units for collectors.
Dual-OS design lets users switch between music-focused Mango OS and full Android 13, enabling both pure playback and streaming service access.
Modular amplifier system allows swapping the stock AMP15 via two screws; included module delivers 2150 mW per channel at 32 ohms.
Beyond the headline features, the DX340 is interesting for how deliberately iBasso separates subsystems that are usually intertwined in Android-based players. The choice of an FPGA-centric conversion stage hints at a preference for deterministic signal handling over off‑the‑shelf DAC voicing, allowing clocking, filtering, and oversampling behavior to be defined in code rather than fixed silicon. Paired with fully isolated power domains, this architecture is clearly aimed at minimizing digital noise injection into the analog path—an approach more common in desktop gear than in portable players. Some sources frame this as a pursuit of “black background,” while others emphasize transient precision and microdynamic stability; in practice, both interpretations stem from the same engineering decision to treat the DAP less like a smartphone and more like a scaled-down component stack.
The modular amplifier concept also deserves a more technical reading than simple user convenience. Swappable output stages change not only power delivery but output impedance, current behavior, and even gain structure, which directly affects how sensitive IEMs or low-impedance planars are driven. This positions the DX340 as a platform rather than a closed product, with the stock module acting as a reference point rather than a final statement. The Titanium Limited Edition adds another layer to the discussion: titanium’s stiffness and damping characteristics differ noticeably from steel, potentially altering how mechanical vibrations are dissipated inside the chassis. Some sources treat this as purely aesthetic or collectible value, while others view it as part of a broader attempt to control resonance in a high-mass portable device—an argument that will resonate with readers accustomed to debating chassis materials in full-size amplifiers.
