Quiet! Active Noise Cancellation+® (ANC+) at work!
Exceptionally quiet power. The measured noise floor is 100x quieter than the common noise filter.
Our home DAC will improve the sound quality of your music.
Elder Scrolls on the xBox? The latest box office hit on your 4K TV? Relaxing with Rachmaninoff? Whatever your passion, the iOne will improve the quality of the soundtrack.
All things to all people
The nano iOne caters for all.
It works with smartphones, tablets, gaming consoles, Google Chromecast, Nvidia Shield and Smart TVs. Not to mention just being part of a regular hifi set-up. Phew!
Zing
The nano iOne plays high quality audio files up to DSD256 and keeps them in the ‘Bit Perfect’ format you appreciate. Now with added MQA!
It will add warmth, depth and zing to your audio.
Plus, it’s Roon tested for easy set-up of Roon should you wish to give it a go.
Connected
Connect via RCA and SPDIF (optical/coaxical) to an A/V or amplifier or choose USB.
Enjoy the freedom of Bluetooth®. The iOne will remember up to 8 wireless devices at one time – handy for today’s ‘connected’ home.
Bluetooth. Better.
Connect the iOne to your amp and relax.
Stream Spotify, Apple Music or Tidal wirelessly from the comfort of your favourite armchair using your phone, iPad or laptop.
The iOne has both aptX™ and AAC™ Bluetooth® for CD-like quality. With standard Bluetooth®, the sound quality drops by 30% but not so with the iFi Bluetooth® implementation.
Your sound. Your way.
Whether you are finishing first on Forza 4, singing along to The Greatest Showman or jamming with John Coltrane, the iOne is the one that you want.
Connect your phone or device wirelessly via aptX™ and AAC™ Bluetooth®. Whatever your device, we’ve got it covered. Read more on iFi’s take on Bluetooth® here.
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.
Extensive jitter-eradication technologies are applied to the digital stage, including our GMT (Global Master Timing) femto-precision clock and intelligent memory buffer. This represents a total ‘out-of-the-box’ systematic digital solution that solves jitter once and for all.
A galvanically isolated SPDIF output means that electrical circuits are separated to eliminate stray elements – a signal can pass but nothing else. Interference-free audio.
And with added Reclock® and Regenerate® the signal remains true and strong.

Test du iFi Audio Nano iOne
“Extremely easy to use, the Nano iOne also offers very good aptX Bluetooth connectivity with minimal latency and no dropouts… even at a long distance… Once again, iFi Audio has hit the nail on the head.”

Great USB DAC, also with good quality Bluetooth.
I wanted to use this with a computer and traditional amplifier and speakers, but also thought it would be nice to allow steaming from my phone or tablet too, since I did not have that arranged in my office system.
I connected directly via USB to my Windows 10 PC then into an older stereo amp and speakers. No drivers were needed and it all just worked by selecting it as the output in Windows. I configured my PC to leave the USB power on when shutdown, so I can use it directly from my phone without booting the PC. It also comes with a power supply if you just wanted to use it as a DAC and Bluetooth receiver in your hifi setup.
This product is great for this kind of use. The sound quality is excellent even with Bluetooth. Nice too that, depending on how you stream to the device, the front panel uses colour to show you what the source quality is too.
I liked this enough to add it to my main system for a while and played with a Mac Mini/Tidal/MQA source. It really is an amazingly good sound for something so small and reasonably priced. It also feels very solid and the flick switches add a little touch of class too. Tired it with Bluetooth, USB and COAX and all sounded very fine to me. I think you would be hard pressed to do much better at this price. Just as a test, I also plugged it directly in to my iPad via USB and that also worked surprisingly well too.
In summary, this seems excellent to add a DAC to a PC or Mac, or if you need to stream from a computer or phone with an older conventional hifi amp and speakers.

Sound quality
Easy to set up and easy use. Makes a substantial difference to the sound quality through bluetooth. Much better listening experience with reduced distortion and better top and lower end.

IFI IONE DAC: POCKET SIZED BUT STILL MORE THAN A HANDFUL
“For such small footprint the iFi iOne provides a wealth of features and flexibility, giving you a gamut of connectivity options. Whatever you do plug into this DAC, though, you will find a neutral and well balanced sound quality that gives you more music for your money due to its low noise output. Great value for 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.
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.
Bit-Perfect
If a file is “Bit Perfect’ it means it has stayed the same. For example, if a PCM file is played through a DAC to improve the sound quality and the DAC does not change the file format. The file is ‘Bit Perfect’.
aptX
aptX Bluetooth transmission is found in most Android phones, media players, Apple computers (macOS on iMacs and MacBooks) and on higher-quality Bluetooth headphones. It is not available on iOS (iPhones and iPads use Advanced Audio Codec).
AAC
AAC is one of the most commonly-supported Bluetooth codecs in the wireless headphone and speaker markets. It’s also the default audio compression codec used by Apple’s iTunes and YouTube and is supported across both iPhone and Android smartphones.
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.
Active Noise Cancellation
Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.
Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.
Galvanic Isolation
Galvanic isolation is a design technique that separates electrical circuits to eliminate stray currents that contain noise. Signals can pass between galvanically isolated circuits, but stray currents, such as differences in ground potential or currents induced by AC power, do not pass. This means little or no noise interference to the audio signal from stray currents.
