iBasso DX180 Quad DAC Digital Audio Player

The CS43131, a flagship DAC chip from Cirrus Logic, boasts an impressive dynamic range of 130dB and an incredibly low THD+N of -115dB. The DX180 utilizes the same DAC matrix technology as DX260, with 4pcs CS43131 chips working in unison to exceed the theoretical technical limit of the CS43131. The AP measured THD+N reaches an impressive -121dB, demonstrating the superior technology and design concept utilized by the DX180, surpassing that of its competitors.

After years of algorithm development, our FPGA-Master has entered generation 2.0. As the audio system controller, it directly requests audio data from the SoC and plays a major role in signal reproduction and maintaining signal integrity. It synchronizes and generates all audio clocks utilizing two NDK femtosecond oscillators to achieve a fully synchronized single clock source. The FPGA-Master 2.0 also has picosecond-level precise control and adjusts the DAC clock, data, and constructs the FIR filter.

The FPGA-Master 2.0 algorithm fully exploits the capabilities of the 4pcs CS43131 DAC chipsets. With the sum greatly enhancing the normal performance of the CS43131 allowing the chip set to become a super performer.

• Synchronous parallel output mode: This reduces "discrete distortion" between DACs to improve overall performance.
• FIR 2x mode: With FPGA-MASTER 2.0, picosecond-level precise control and adjustment of the DAC clock and data is achieved, making each DAC data stream independently adjustable. Through the "delay parallel" of DACs, the DACs form a hardware analog FIR filter, which averages the differences between multiple DACs, reducing distortion and effectively improving sound details and the quality of the bitstream.

The true measurements of DX170 weere close to the theoretical limits of the CS43131 chipset. However, the DX180 has gone a step further, completely surpassing technical obstacles and establishing an insurmountable lead in this price range.

The DX180 THD+N measurement ranks second among portable audio players, with only the DX260 having a better THD+N measurement.

The DX180 boasts an impressively low noise floor of just 0.79uV. Even at the highest volume with high gain, the balanced port noise floor is only 1.1μV. The noise floor is significantly lower than other players in this price range and due to this, the DX180 has a distinct quietness. The black background provides an exceptionally vibrant music playback experience.

The DX180 employs the Qualcomm Snapdragon 665 SoC, featuring an 8-core architecture and an advanced 11nm process. This results in reduced heat generation and enhanced stability for seamless operation. With the Micro SD card expansion, the DX180 can provide an impressive 2TB of extra storage space. No matter how much music you adore, the DX180 can effortlessly accommodate it all.

DX180 is equipped with Android 13 system OS, which allows you to freely install streaming APPs and enjoy the convenience of Android. The DX180 bypasses Sample Rate Conversion at the system level whether it is Mango Player or third-party streaming APPs - so you can enjoy the system-level "Non-SRC" feature, and enjoy Hi-res music.

The DX180 features a dedicated USB receiver which enhances the USB-DAC functionality of the DX180. Experience low latency audio when using the DX180 as an external DAC for laptops and phones. ASIO/WASAPI output is supported on Windows PC via a dedicated driver.

The DX180 is compatible with PD3.0 and QC3.0 fast charge. The battery reaches 83% charge in just 60 minutes, and a full 100% charge is achieved in a mere 84 minutes. Additionally, the improved power management system allows for an impressive battery life of up to 15.5 hours for the balanced phone out usage and an astonishing 30 hours for Line Out playtime.

DX180 features a striking new designm with an easily removeable back cover for convenient future battery replacement.
