Stream, stream, stream…

The nano iDSD Black Label is for those who enjoy great music on-the go.

From your phone, amplify your Spotify, Apple Music or Tidal using an Apple CCK cable or OTG cable for Android.

At home or in the office, use the USB3.0 cable provided to connect to your PC.


Res’ing it up!

The nano iDSD Black Label plays Hi-Res audio up to DSD256
so you can enjoy your tunes in the original format just as the artists intended.

Getting into MQA? The nano BL is MQA ready.  Use it with Tidal ‘HiFi’ on your computer or mobile.

Also, Roon tested for simple set-up should you wish to give Roon a whirl.


The mighty nano

The nano iDSD Black Label is small but mighty with 10x more amplification power than an iPhone.

It can drive most headphones and has our iEMatch technology built-in, so it can work with In-Ear-Monitors (IEMs).

The in-built iFi iPurifier means it delivers clean, quality music with no buzz, no hiss and no fuss!


Brilliant balancing act

The iFi exclusive S-Balanced circuit provides all the benefits of balanced outputs such as low-noise and less distortion when used with headphones and IEMs fitted with balanced wiring.

For single-ended headphones, S-Balanced cuts crosstalk in half. The benefits are ‘clearly’ audible.


Listen. Measure.

Fancy getting technical? The nano BL has a Listen option (Minimum Phase Bezier Filter) and a Measure option (Linear Phase Transient-Aligned Filter) for those who like to try a variation to the playback.

We say just switch it on, plug in your device, and listen away.

There is no going wrong with 10 hours of battery life.
