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.
Zero Jitter® equals good audio. Is it essential to have a very precisely buffered digital signal before it goes to a DAC.
We pushed the envelope even further by doing this not only with the nano iDSD BL‘s USB input, but the rest of the digital interfaces as well.
This unit has up to 10 hours of non-stop playing time. Always make sure you switch it on first and then plug in your device.
The Burr-Brown True Native® chipset means file formats remain unchanged or ‘bit-perfect’. This means you are listening to music as the artist intended in the format in which it was recorded.
At iFi we use Burr Brown extensively in our products having selected it for its natural-sounding ‘musicality’ and True Native architecture. Our experience with this IC means we know how to make the most of it.
Hi-Res True Native® playback of all music formats from MP3 to DSD256, PCM384 and DXD384.
Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA.
Our video tutorials on You Tube show you how.
iFi’s exclusive S-Balanced® circuit delivers maximum performance from single-ended and balanced headphones alike.

Reviews
iFi audio nano iDSD Black Label under test
“The iFi Nano iDSD BL is a product that we recommend more than warmly by the editorial staff and even more if you are looking for a DAC / mobile headphone amplifier given its format, its autonomy, its weight and the excellent musical performances it offers. offers, especially in headphone output. It is also a pure happiness for its price in line output, even if one would have preferred an RCA output rather than jack, simple practical question.

Increases sound quality.
Makes audio quality from your cellular telephone sound better if you are using headphones. It requires recharging about once a day with a usb b cable.

Needed a better audio setup for my PC. I made the right choice!
Had been running my audio via a cheap Fiio optical DAC into a modded (upgraded the internal op-amp to OPA2227) Creative Labs speaker system. I decided to smarten it all up a bit with something more advanced. After some research I settled on this unit.
The dual headphone outputs gave some improved options further down the line if I decided to go more exotic headphone wise. The pure DAC only output is great to pump into my amplified speaker setup. I doubt I’ll use it with my phone or mobile but the option is there. The range of digital media it can handle is pretty wide too.

Great Sounds
Love the quality of sounds I got with just Pandora Premium and beyerdynamic DT 770 PRO 250 Ohm and KZ ZS10.
Love all the extra adapters that came with the unit.
Love the compact size.
Don’t like the long USB cable came with it. Too stiff. I replaced it with my own cable.
Don’t like how you have to remember to plug it in first before turning it on if you don’t want to use the internal battery.
Over all still loves it.

Perfect Portable Solution!
I bought the iFi Nano as a second source for my headphone collection. I was mainly attracted by the ability to be able to stream music from my phone and it certainly hasn’t disappointed. Build quality is top notch and the specs are very impressive . I would quite happily use the iFi as my main source as it sounds every bit as good as my two box desktop solution.
I am using it to power a pair of HiFiMan Sundara headphones. I find that I only need to use about 25% of the available volume. Trying to run them directly from my phone was futile, so this little box has done the trick. It is also nice to be able to support a UK Hi-Fi company. I honestly don’t think that there is a better solution around at the moment for the money.

DAC (Digital-to-Analogue Converter)
DACs convert digital information, stored or streamed by computers, into music we can hear through speakers or headphones.
Every device that’s a source of digital sound has a built-in DAC (TVs, games consoles, CD players, phones, portable music players etc). Dedicated external DACs sound much better than standard DACs used in digital devices such as phones.
Apple CCK and Android OTG
So, why don’t we provide these two cables with our products?
The Apple CCK cable can only be purchased from Apple. We can’t make one ourselves as it has a special chip in the cable that we’d need to use for them to actually work with Apple hardware. Sadly, Apple has not released this chip to anyone.
We can and do make two versions of an Android OTG cable – Type C and micro.
DSD (Direct Stream Digital)
DSD is a very high-quality digital audio format that’s even better than CD quality. The higher the ‘DSD rate’ – DSD64, 128, 256, 512 and 1024 – the greater the amount of music information available, which means better sound quality.
Files can be remastered to higher file rates to improve sound quality. The pinnacle of this is DSD1024. Not many machines out there are capable of this feat.
MQA (Master Quality Authenticated)
MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. More here.
Tidal Masters
Tidal is a subscription-based audio streaming platform, similar to Apple Music and Spotify, but with lossless-quality audio. Tidal Masters is the section with the highest-fidelity music streamed including some files in partnership with MQA.
Lossless-quality means that no music quality is lost in this format.
IEMs
IEMs stands for In-Ear Monitors.
These fit inside your ear. You’ve been using them for years. You just called them something else.
You will also see these referred to as earphones, ear buds and CIEMs. CIEMs are Custom In-Ear Monitors – IEMs made specifically to fit your ear shape.
File formats
MP3 – this is the most popular format, every device in the world can use it.
DSD – Direct Stream Digital is a very high-quality audio format, better than CD quality. The higher the number (sample rate), the better the recording – DSD64, 128, 256, 512 and 1024.
PCM – Pulse Code Modulation is the most common format for CDs and DVDs.
DXD – Digital eXtreme Definition is a very high-quality PCM format. It was developed to edit hi-res (high quality) recordings recorded in DSD.
Analogue 'v' Digital Volume Control
For cost and convenience, modern DAC chips have a built-in digital volume control. The drawback is that a digital volume control works by ‘truncating’ the signal. Or ‘chopping Bits’ of resolution. For a 16-Bit music file at 50% volume level means the listener is actually listening to 14.5-Bits!
All iFi products bypass the digital volume control and use a separate analogue volume control which does not ‘lose Bits’ so a 16-Bit file stays unchanged which delivers maximum resolution.
Losing Bits of resolution (quality) is like having missing pixels on a computer or TV screen.
