iBasso DX270 R2R DAP

arrays operate in balanced mode for each channel. Through the natural advantages of a balanced design — excellent common-mode noise rejection, better signal-to-noise ratio, and higher soundstage density — it is possible to reduce noise and interference from the source of the signal.

The result is a sleek, lightweight player giving dynamics, texture and details with excellent linearity.

// MORE ABOUT DX270

8-Channel, Fully Differential R2R

The DX270 features a fully balanced 8-channel R2R architecture, using dual R2R DACs per channel to eliminate zero-crossing distortion and maintain smooth, linear signal transitions. This differential design delivers exceptional stability even at low levels and achieves an industry-leading 130dB dynamic range.

A Leading Technology for Superior Sound Quality

The DX270 uses a hybrid 20-bit R2R plus 4-bit String DAC architecture, with a String DAC handling high-bit processing for wide dynamic range, low distortion, and minimal spurious noise. By employing 344 high-precision resistors, nearly double that of standard R2R designs, iBasso achieves a more delicate, natural, and pure sound.

Outstanding Linearity

The complex waveforms of music are composed of many frequency components. When the DAC’s output curve isn’t perfectly linear, extra harmonic distortion, intermodulation, and waveform distortion occur. The DX270, with ultra-high resistor matching, reliable switch precision, and optimized circuit architecture, exceeds mainstream R2R linearity. The output curve closely matches the ideal curve, free of extra harmonics or distortion, delivering a “night-black” background while delivering a natural and realistic musical presentation. 

Non-SRC Android 13 + Mango OS

The DX270 utilizes Android 13 OS with a refined UI that supports installation of various streaming APPs. It bypasses SRC at the system level, allowing apps like Mango Player to work at their best. Additionally, it features Mango OS, a Linux-based music system with many advanced algorithms, which are dedicated for audio playback. With lower SoC load, no WiFi interference, no Bluetooth interference, and lower EMI, the results are a purer sound.
