Portable R2R 1bit DAC and tubular headphones amplifier

The Ibasso D17 is a portable premium DAC and headset amplifier that provides a clear, detailed sound with a special R2R and 1bit Dual DAC architecture and two Nutube 6P1 tubes. The four-band is fully balanced R2R design and the 64 PWM-DAC unit bring music to life, gently and naturally returned.

The device has three DAC modes (NOS, All to R2R, All to 1Bit), USB-C, coaxial and optical inputs, and 4.4 mm balanced and 3.5 mm single-ended outputs. Dual Battery architecture and FPGA-Master 3.0 control provide stable and clean sound transmission, while analog and digital volume control provides precise control.

The D17 is a compact 470g device with an OLED display and a three-layer vibration damping system that minimizes the microphone effect. In every detail, precision and quality feel, so the device is really vivid, warm and natural.
