Features Fully Balanced 4-Channel R2R DAC For Accurate Decoding

iBasso D17 Atheris features a fully balanced 4-channel R2R DAC with 284 ultra-precise resistors (0.01% tolerance), delivering a natural, analogue-like sound. Its 1-bit DAC mode uses 8 sets of 8E totaling 64 PWM-DAC units for detailed, high-resolution audio. In Ibit mode, the four channels L+, L-, R+, and R- each have 16E, totaling 64 PWM-DAC units working together Professional audio DSP chip, with a theoretical dynamic range of up to 192dB and THD+N reaching -174dB.

Offers Three DAC Modes For A Different Personalised Listening Experience

iBasso D17 Atheris offers three DAC modes for different listening preferences. It features NOS mode (PCM utilises R2R DAC decoding, DSD utilises 1-bit DAC decoding), OS mode (all-to-R2R) and SD mode (all-to-1-bit). iBasso D17 Atheris ensures a customised listening experience based on your preference.

Houses Precisely Selected 284 Ten-Thousandth Ultra-Precise Film Resistors

iBasso D17 Atheris uses precisely selected 284 ultra-precise film resistors with a tolerance of one ten-thousandth (25ppm). It achieves THD+N of -104dB in R2R mode with its fully developed in-house hardware resistor compensation circuitry and software compensation algorithms. iBasso also features custom film capacitors and vintage SPRAGUE capacitors. iBasso D17 Atheris offers a high-quality analogue voicing, providing a warm sound with exceptional musical quality.

In-House Developed FPGA-Master 3.0 Architecture For Distortion-Free Audio

iBasso D17 Atheris features an in-house FPGA-Master 3.0 architecture. It uses two Accusilicon ultra-low phase noise femtosecond oscillators for a clear and pure single clock source. Nanosecond-level high-precision delay control and real-time clock regeneration technology ensure R2R and 1-bit decoding. This allows detailed and distortion-free audio at extremely low levels.

Nutubes Enhanced By BUF634A Amplifier With Ultra-Low Noise Analog Power Supply

iBasso D17 Atheris embeds dual Nutube 6P1 tubes with a lifespan of up to 30,000 hours, providing warm, musical sound enhanced by a powerful BUF634A buffer amplifier. It delivers up to 1200mW + 1200mW at 32 Ω, easily driving demanding headphones. Ultra-low noise analogue power supply, with noise as low as 0.6µV, which is lower than the 0.8µV of the LT304x by Linear Technology, iBasso D17 Atheris delivers enhanced and warm audio.

Utilises A Composite Isolation System For Exceptional & High-Quality Audio

iBasso D17 Atheris uses a composite isolation system composed of a double-layer PCB along with damping materials. The two PCB layers are connected via pin connectors, effectively dispersing lateral stress and reducing resonance. The tube is placed on the second PCB layer using damping materials, providing a secondary reduction of microphone effects below the threshold of human hearing level. iBasso D17 Atheris achieves exceptional stability and high-quality audio.

Dual-Battery System With Anti-Vibration Design And Precise Volume Control

iBasso D17 Atheris features a dual battery power supply architecture powered by separate batteries. This design ensures a stable current supply while effectively isolating digital interference for the headphone amplifier section. It delivers a pure, stable output, reducing distortion even under high gain or heavy load. iBasso D17 Atheris delivers clear and high-quality audio.

Offers Accurate Volume Adjustments Supporting Analogue and Digital Form

iBasso D17 Atheris offers accurate volume adjustments supporting both analogue and digital forms. The analog form features a 24-position 4-section stepped attenuator, one-tenth the size of the traditional attenuator, while retaining all its advantages. There is less than +/-0.1db dB difference between left and right channels. Digital volume adjustment is performed via a professional DSP module. iBasso D17 Atheris  allows precise volume output with the combination of digital and analogue volume control

Versatile Connectivity With PCM Support For Expansive Soundstage

iBasso D17 Atheris features balanced 4.4 mm and single-ended 3.5 mm outputs, delivering a rich, expansive soundstage. With USB-C, coaxial and optical connectivity and support for PCM up to 768 kHz and DSD512, iBasso D17 Atheris offers versatile, high-quality performance while also featuring a 1.3-inch OLED display screen.
