Discrete 1bit Architecture With 160 PWM-DACs

The DX340MAX, as the ultimate evolution of the DX340, has been further enhanced from the original 128 discrete PWM-DACs to an impressive 160 PWM-DACs. The number of PWM-DACs is more than eight times that of other portable discrete DACs devices. This is not just an increase in quantity but also a more stringent requirement for clock precision and algorithm scheduling.

Through a complete overhaul of the circuit design and wiring optimization, the entire device's AP measured THD+N as low as -122dB, which is comparable to desktop DACs using 1bit architecture priced at 13,000 USD. For discrete 1bit architecture, the mountain is high, but the summit has been reached. 

FPGA-Master 3.0

The DX340MAX is equipped with FPGA-Master 3.0 technology, which is built on years of in-house developed algorithms by iBasso. The new FPGA chip has 7.5 times the number of LUT logic units compared to version 2.0.

FPGA-Master 3.0 serves as the main audio controller, directly requesting audio data from the SoC. It is paired with two Accusilicon femtosecond oscillators with the phase noise as low as -158 dBc/Hz@1kHz, achieving fully synchronized single-clock operation. This creates picosecond-level precise control for the PWM-DACs, minimizes jitter as much as possible, and builds a pure digital audio system, ensuring every note is accurate, clear, and detailed.

Leveraging the powerful performance of the new FPGA the DX340MAX incorporates numerous new algorithms for even and odd harmonic adjustment, resulting in rich overtones and more distinctive sound characteristics. Increasing even harmonics makes the sound closer to that of a tube amplifier, while increasing odd harmonics adds more passion and vitality.

SoC + Audio DSP + FPGA-Master 3.0

Some players, to simplify and lower cost, implement audio DSP functions by simulating DSP algorithms within the SoC using software decoding. Because the system SoC needs to run a complex operating system, its real-time performance and system-level jitter are severely compromised. Using the SoC for "software decoding" of DSP algorithms results in unavoidable deterioration of audio quality.

To thoroughly resolve this issue, the DX340MAX is equipped with a dedicated professional-grade audio DSP chip. Thanks to this DSP's exceptional 192dB dynamic range and -174dB THD+N, it can achieve perfect audio conversion, while significantly reducing the load on the SoC.

Meanwhile, FPGA-Master 3.0 serves as the main audio controller, independently managing all audio processing permissions. From a physical architecture perspective, it effectively solves the problem of sound pollution caused by the SoC handling complex operating systems.

Driving With Precision & Mastery

A key upgrade in the DX340MAX over the AMP18 is the addition of a dedicated differential buffer amplification stage, which is composed of two operational amplifiers with a CMRR (Common Mode Rejection Ratio) of up to 120dB, that achieving full differential transmission. This design effectively reduces noise interference caused by differing reference grounds and isolates the impact of the rear-stage power output on the front stage. 

The headphone amplifier adopts a 4-channel fully differential architecture with a cascaded current feedback design, improving latency issues associated with deep negative feedback circuits. A total of 80 transistors are used in a two-stage amplification structure to ensure linearity during signal amplification. Coupled with a complementary output circuit, it effectively reduces signal clipping distortion.

With numerous advanced technologies, the DX340MAX features a balanced output impedance of only 0.9Ω and a single-ended output impedance of just 0.4Ω, allowing it to deliver both powerful dynamics and delicate details simultaneously.

Open System + Closed System, All-in-One

Using the Android 13 system and supporting installation of streaming APPs, you can enjoy the convenience of the Android system. The DX340MAX bypasses Android SRC system-wide at the software level, allowing both Mango Player APP and streaming APPs to enjoy system-level “Non-SRC” features.

Additionally, the DX340MAX features our in-house developed dedicated pure sound system, Mango OS, built on a Linux platform, specifically developed for music playback. Mango OS has accumulated extensive optimizations in music decoding and underlying algorithms, reducing CPU load and focusing solely on audio playback. This pure sound system has no WiFi or Bluetooth interference, offers low EMI, and provides a purer listening experience.
