iBasso D16 Portable DAC Amp with 128 PWM-DACs, super Class-A amplification and up to 9 hours battery life. This compact device delivers high resolution audio support for PCM 768kHz and DSD512. It offers versatile connectivity through USB coaxial and optical inputs plus balanced and single-ended outputs that also function as line outs.
About iBasso D16
The iBasso D16 brings advanced 1-bit discrete PWM-DAC technology into a portable format. Its FPGA-Master 2.0 architecture manages 128 independent PWM-DACs arranged in 16 cascaded sets of 8E units. This setup operates in FIR mode and relies on high-precision resistors for accurate signal reconstruction. Users gain exceptional detail retrieval and natural sound that reveals subtle textures in music while staying true to the source material.
The audio performance stands out with support for PCM files up to 32bit/768kHz and native DSD up to DSD512 through the USB input. Coaxial and optical connections handle high resolution signals effectively. Line outputs achieve very low distortion levels and high dynamic range that reaches 123dB. The frequency response covers 15Hz to 40kHz so listeners enjoy full and accurate reproduction across the entire audible spectrum.
Power comes from a super Class-A discrete amplifier built with 20 low VCEsat BISS transistors capable of delivering up to 2A of current. The balanced 4.4mm output produces up to 6.8Vrms while the 3.5mm single-ended port offers solid drive for various headphones. Dual volume controls provide precise adjustment through a 24-position stepped attenuator on the DAC side and a digital control for the amplifier section.
The sturdy aluminum alloy chassis measures 139 by 82 by 28 millimeters and weighs 312 grams. A clear 1.3-inch OLED display helps with easy navigation of settings. Multiple inputs support USB-C data transfer separate charging port and combined coaxial plus optical connections. Both headphone outputs double as line outputs when needed.
An internal battery runs for up to 9 hours on a single charge and accepts quick charging through QC3.0 standard. This combination makes the unit suitable for extended listening sessions whether used on the go or as a flexible desktop companion. The overall design delivers high-fidelity audio with versatile connectivity options that adapt to different listening setups.
