Portable DAC and Headphone Amplifier

Elevate Your Audio Experience

The nano iDSD Black Label is a portable DAC and headphone amplifier designed to enhance your music wherever you go. Whether on your daily commute or in the office, it delivers superior sound quality and amplifies your personal audio experience.

Hi-Res Audio Everywhere

Play Hi-Res audio up to DSD256 and enjoy MQA streaming with Tidal HiFi or Roon. The Burr-Brown True Native® chipset ensures "bit-perfect" playback for pure, original sound as the artist intended.

Powerful Performance

With 10x more amplification power than an iPhone, the nano BL can drive most headphones and supports In-Ear-Monitors (IEMs) with iEMatch technology for noise-free listening. The built-in iPurifier guarantees clean, high-quality audio with no buzz or hiss.

Balanced Audio for Clarity

The iFi-exclusive S-Balanced circuit reduces noise and distortion for balanced headphones while minimizing crosstalk for single-ended connections. Enjoy crystal-clear audio with every detail intact.

Customizable Listening

Choose between the "Listen" (Minimum Phase Bezier Filter) and "Measure" (Linear Phase Transient-Aligned Filter) options for tailored audio playback. With up to 10 hours of battery life, the nano BL is perfect for extended listening sessions.
