The DX270 is not a typical R2R player, but a deep reconstruction of the R2R decoding made by iBasso, to realize R2R. It adopts a 20-bit R2R + 4-bit String DAC hybrid architecture, which combines an 8-channel fully differential discrete R2R, FPGA-Master 3.0 in-house developed algorithms and hardware resistor compensation network. This results in a dynamic range of 130 dB and a THD+N better than -97 dB, which completely overcomes the zero-crossing distortion problems common in R2R devices, ensuring near-perfect linearity. The DX270 features a fully symmetrical 8-channel R2R architecture, using two R2R DACs per channel to eliminate zero-crossing distortion and maintain smooth, linear signal transitions. This differential design provides exceptional stability even at low levels and achieves an industry-leading 130 dB dynamic range.
The DX270 uses a hybrid 20-bit R2R plus 4-bit String DAC architecture, where the String DAC handles high-bit processing for wide dynamic range, low distortion, and minimal noise. By using 344 high-precision resistors—almost double the number of standard R2R resistors—the iBasso achieves a smoother, more natural, and clearer sound.
The DX270 runs Android 13, with a refined user interface that supports the installation of various streaming applications. It bypasses SRC at the system level, allowing applications like Mango Player to perform at their best. It also features Mango OS, a Linux-based music system with a number of advanced algorithms specifically designed for audio playback. With lower SoC load, no WiFi interference and no Bluetooth interference, and lower electromagnetic interference, the result is clearer sound.
