iBasso DX270 R2R Ultra

Overview

Advanced 8-Channel R2R Ultra DAC

Versatile Dual-OS Platform

Key specifications

• Key Features:
• Hybrid 20-bit R2R + 4-bit String DAC: Combines the natural tonal texture of an R2R DAC with the high linearity of a string DAC for wide dynamic range and low distortion.
• Fully Differential Design: An 8-channel fully balanced architecture utilizes two R2R arrays per channel, eliminating zero-crossing distortion and achieving exceptional signal linearity and a 130dB dynamic range.
• Hardware Resistor Compensation: Features a hardware network with 344 high-precision resistors and FPGA-Master 3.0 algorithms for real-time calibration, ensuring decoding accuracy.
• Android 13 with SRC Bypass: Runs a full Android 13 system that bypasses sample rate conversion (SRC), allowing bit-perfect playback from any streaming app without resampling.
• Pure Audio Mango OS: Includes a dedicated, lightweight Linux-based Mango OS for pure audio playback, free from wireless and system process interference.
• 12V DC External Power Input: Supports an external 12V power adapter for desktop use, unlocking higher output voltage and maximum power.
• Substantial Balanced Output: Delivers up to 1,575mW per channel @32Ω (with 12V DC) and 1,050mW on battery from the 4.4mm output, capable of driving demanding headphones.
