ZEN One Signature

ONE to rule your home audio

Only DAC you’ll need (Bluetooth + USB + S/PDIF)

ZEN One Signature

Our ZEN One Signature takes the DAC stage from the ZEN DAC V2, adds S/PDIF inputs (optical and coaxial) alongside the USB port, stirs in Bluetooth technology from the ZEN Blue V2 and seasons the pot with Signature-grade circuit enhancements to create a delicious audio brew.

The result? The ZEN One Signature is a pure DAC (no built-in headphone amp and volume control) that serves as a home audio hub for all your digital devices, from smartphones and tablets to PCs and Macs, disc players and audio servers to TVs and games consoles.

Signature Special

The Signature series always includes extra special additions:

  • Low-jitter femto clock crystal provides >20dB performance
  • 16 Core 2000MIPS XMOS low-latency microcontroller – 4x more processing power
  • C0G capacitors – high-linearity, excellent temperature/frequency characteristics
  • MELF resistors – high-precision and low-noise
  • Taiyo Yuden and Murata inductors – low-impedance power supply rails
  • High-gain antenna for extended range
MQA

Thanks to the XMOS 16 core tech, the ZEN One Signature is an MQA Decoder.

This enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The LED glows green or blue to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.

MQA rendering technology (used in the original versions of some other iFi products) connects to an MQA Core signal and completes the final unfold of an MQA file. Core decoding is included in streaming services such as TIDAL, as well as select media players.

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.

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.

We use Qualcomm’s new QCC5100 Bluetooth processing IC in combination with proprietary circuits to create an audibly superior ‘Bluetooth engine’.

All the current high-definition Bluetooth audio formats are supported – Qualcomm’s aptX Adaptive and aptX HD, Sony’s LDAC and HWA’s LHDC, regular aptX and aptX Low Latency, AAC (Apple iOS devices) and SBC (the ‘plain vanilla’ Bluetooth codec).

Of the 24-bit-capable codecs, aptX Adaptive and aptX HD support up to 48kHz, while LDAC and LHDC reach 96kHz.

iFi’s ‘Bluetooth engine’ can also be updated over-the-air, so future codecs may be added.

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. The ZEN One Signature adopts MQA technology to receive and decode MQA audio and provide master-level sound.

Visit mqa.co.uk for more information.

It is a superior method to the traditional single-ended circuit approach. Balanced circuits reduce noise and crosstalk. Less Interference – clearer sound.

You normally find this set-up in products at the higher end of the price spectrum such as the Pro iCAN Signature but iFi is now using this across its range to produce the best quality audio for all our customers.

Vishay MELF resistors – complex, costly but superior.

These metal electrode leadless face resistors have excellent accuracy, stability, reliability, and pulse load capability. They provide optimal power rating and pulse load capability. They show some of the lowest noise and distortion of any resistor available in the market, period.

TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.

Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.

They are pricey but are a perfect addition to our products.

Panasonic OS-CON caps totaling 5,410uF give very-low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency response characteristics. In addition, OS-CONs have a long-life span and its ESR changes little even at low temperatures since the electrolyte is solid.

They are not often found in products costing <US$1000.

Extensive jitter-eradication technologies are applied to the digital stage, including our GMT (Global Master Timing) femto-precision clock and the intelligent memory buffer.

The low-jitter crystal clock has been updated to provide >20dB better performance

We use ELNA Japan Silmic II capacitors for the power supplies.

The primary constituent of the newly developed dielectric is silk fibre. This material was believed as unfathomable as an aluminium electrolytic capacitor. The new material beats silk fibre and mixes it with Manila hemp fibre to provide the dielectric to an aluminium electrolytic capacitor used for high-grade music. The result is second-to-none superior acoustic properties and excellent linearity.

muRata control-type, low-ESR high-Q multi-layer capacitors. The ‘ESR control’ aspect of the Murata is something special. Their noise suppression abilities are impressive.

Texas Instruments low-noise ICs offer great unity-gain bandwidth, very low noise and distortion, high output drive capability, Common-mode and Power Supply Rejection Ratios of over 100 dB, wide maximum-output-swing bandwidths and high slew rates.

“…an absolutely brilliant affordable DAC.”

” Something that the One Signature is extremely effective at is avoiding the ‘etched’ presentation that some DACs generate in the pursuit of detail.

“Everything sounds both tonally correct and usefully detailed but there’s no emphasis on any part of the music that puts undue attention on it.”

“With the linear power supply in particular, the One Signature is capable of performance that is pretty much as good as it gets for the asking price and combining this with the additional flexibility of more inputs makes this an absolutely brilliant affordable DAC.”

Ed Selley, HiFi Critic

iFi Audio Zen One Signature Digital-to-Analog Converter

“It pains me to type this as much as it likely pains you to read it, but all I can say is that I think I’m going to buy my review sample. And yes, I know that’s the single most hackneyed way any writer can end a review, but the fact of the matter is that I occasionally review all-analog products, and I need a good DAC that can decode any and all meaningful digital formats.”

“iFi Audio makes the bold claim that this is the only DAC you’ll need. And I can’t speak for all my readers, but in my case that ended up being a true story.”

Best in Class

Let me be unequivocal here; for £350, the One Signature is a bargain, a bobby dazzler, a no brainer, whatever term you wish to use. You get a well judged set of inputs coupled with decoding that is sensationally good; balancing engagement, realism and the means to celebrate good recordings while flattering poor ones. This is the device that affordable amplifiers need in their lives and it is an unquestionable Best in Class.

A Captivating Digital To Analog Converter…

“I have to say; I was quite impressed by the One Signature’s wireless performance. Through this amply resolving system, I didn’t feel like I was missing a lot of detail, nor did I want for a lot of depth or separation.”
“Listening to TIDAL MQA tracks via Roon on the iFi DAC was pure pleasure, as the music just sounded warm, natural, and not overly processed. The somewhat laid-back perspective lets you “hear into” the music instead of assaulting you with a wall of sound, which can be fatiguing after a while.”

Swiss Army Knife of DACs

I have an ifi hip-dac so when I saw this with so many input sources I immediately bought one. I connect via USB and Bluetooth and as the One Signature supports LDAC as does my Samsung tablet and Samsung phone (many newer Android devices should do the same) the result is a high quality Bluetooth audio connections. I principally use Amazon Music Unlimited as my source on both PC / USB and Bluetooth and my very discriminating audio habit is impressed. Very musical and warm, not digital sounding. (I wanted a separate DAC rather than one integrated in an amp as DAC technology evolves.) And it’s a fine value too.
