Embeds The Ultimate R2R Ultra Decoding Architecture For High-Fidelity Decoding

iBasso DX270 R2R Ultra features a deeply re-engineered R2R decoding system combining a hybrid 20-bit R2R + 4-bit String DAC architecture, FPGA-Master 3.0 processing, an 8-channel fully differential discrete R2R design, and a hardware resistor compensation network, achieving 130dB dynamic range and THD+N better than −97dB for highly accurate, natural sound reproduction.

Utilises 20-Bit R2R + 4-Bit String Hybrid DAC For Exceptional Audio

iBasso DX270 R2R Ultra employs a hybrid DAC where high-bit MSB processing uses a String DAC to directly approximate target voltage while a 20-bit discrete R2R handles precision conversion, utilising 344 high-precision resistors to deliver wide dynamic range, low spurious energy, excellent THD+N, and a more delicate & natural audio.

Features 8-Channel Fully Differential Discrete R2R Design For Clean & Accurate Audio

iBasso DX270 R2R Ultra utilises a fully balanced architecture with L+, L−, R+, R− paths, each containing dual R2R DACs to form an 8-channel configuration, eliminating signal gaps at voltage transitions, maintaining stable linearity even at very low signal levels and achieving an industry-leading 130dB dynamic range.

Fused With FPGA-Master 3.0 Digital Control System With Four Digital Filters

iBasso DX270 R2R Ultra integrates the in-house FPGA-Master 3.0 platform featuring data buffering, delay calibration, noise shaping, combined FIR filtering, jitter removal via global clock generation, R2R modulation, real-time hardware calibration, native DSD handling, NOS mode, and four selectable digital filters for tailored listening.

Equips Hardware Resistor Compensation Network For Precise Audio Production

iBasso DX270 R2R Ultra incorporates a precision compensation network using 76 ultra-accurate resistors working alongside FPGA algorithms to improve decoding accuracy, expand dynamic range, reduce distortion and achieve equivalent resistance precision of 1.4 parts per 100,000.

Delivers Exceptional Linearity & Ultra-Quiet Background With Its High-End Components

iBasso DX270 R2R Ultra achieves outstanding linearity through ultra-high resistor matching, precise switching, and optimised circuitry, closely following the ideal output curve to eliminate extra harmonics and waveform distortion, resulting in a night-black background, excellent airiness, and realistic musical presentation with measurable linearity maintained even at −120dBFS.

Fully Differential Architecture & Precise Calibration For Zero-Crossing Distortion Elimination

iBasso DX270 R2R Ultra uses a fully differential architecture and precise calibration to reduce zero-crossing distortion to an ultra-low −120dB level, preserving low-level detail, vocal nuances, and instrument harmonics while preventing muddiness and abnormal noise in near-zero signal conditions.

Embedded With Precision Analog Volume Control System For Precise Audio Control

iBasso DX270 R2R Ultra utilises two dual-channel JRC analog volume ICs forming a 4-channel volume control architecture that synchronously attenuates noise at low listening levels and achieves over 91dB SINAD at typical listening volume (50mV) for clean, natural sound.

Equips Flagship Processing Hardware For Enhanced & Smooth Performance

iBasso DX270 R2R Ultra is powered by a Qualcomm Snapdragon 665 SoC with 4GB RAM and 128GB UFS 2.1 storage for smooth operation and fast response, supports microSD expansion up to 2TB.

Utilises Non-SRC Android 13 & Dedicated Mango OS For Seamless User Experience

iBasso DX270 R2R Ultra runs Android 13 with system-level SRC bypass for bit-perfect playback while also offering Mango OS, a Linux-based dedicated music system that reduces SoC load, eliminates Wi-Fi and Bluetooth interference, lowers EMI, and ensures purer audio performance.

Offers Comprehensive Outputs & USB-DAC Functionality For Versatile Compatibility

iBasso DX270 R2R Ultra provides 4.4mm balanced phone out, 4.4mm balanced line out, and 3.5mm single-ended phone out supporting both headphones and IEMs, with the 3.5mm port also serving as a coaxial digital output up to 384kHz, plus low-latency USB-DAC mode that transforms the device into a high-end R2R DAC for PCs and smartphones.

External Power Input & Super Gain Performance With 12V DC External Power Supply

iBasso DX270 R2R Ultra supports a 12V DC external power supply that boosts amplifier voltage from ±8V to ±12V, enabling Super Gain Mode with output power up to 1575mW + 1575mW at 32Ω, providing ample headroom to drive demanding headphones and handle complex music with ease.
