iBasso D17 Atheris – Dual R2R + 1bit DAC with Tube AMP Power for High-End Portable Audio
The iBasso D17 Atheris is a groundbreaking portable DAC and headphone amplifier that redefines portable hi-res audio. Featuring a dual discrete DAC architecture—R2R and 1bit PWM-DAC—the D17 delivers exceptional sound detail, tonal richness, and true analog warmth. Designed for audiophiles, the iBasso D17 combines cutting-edge technology and craftsmanship in one compact yet powerful unit.
At its core, the iBasso D17 incorporates a fully balanced 4-channel R2R DAC with 284 ultra-precise resistors (0.01% tolerance), offering a natural and analog-like presentation. The 1bit DAC mode utilizes 64 PWM-DAC units for an immersive, high-resolution experience. Whether in NOS, OS (All to R2R), or SD (All to 1bit) mode, the D17 adapts to your listening preferences.
Tube enthusiasts will appreciate the dual Nutube 6P1 tubes, delivering warmth and musicality backed by a powerful BUF634A buffer amp. Output reaches 1200mW+1200mW at 32Ω, easily driving demanding headphones. The FPGA-Master 3.0 ensures nanosecond-level I/O precision and clock synchronization, paired with Accusilicon femtosecond oscillators for superior jitter control.
Key features include a dual battery architecture for pure, isolated power delivery, a three-layer anti-vibration structure, and analog + digital volume controls with stepped attenuator precision. The iBasso D17 Atheris is a reference-grade portable DAC and amp for audiophiles demanding the best from their music.
Whether you’re listening via the balanced 4.4mm output or single-ended 3.5mm, the iBasso D17 provides a rich and expansive soundstage. Compatible with USB-C, coaxial, and optical inputs, and capable of decoding PCM 768kHz and DSD512, the D17 is built for versatility and future-proof performance.
The iBasso D17 Atheris isn’t just a portable DAC/AMP—it’s a revolution in portable high-end audio. Experience the synergy of analog warmth and digital precision with iBasso’s most advanced portable DAC yet.
