Small. But mighty.

The DAC section of the GO bar uses a powerful 16-core XMOS micro controller to process the audio data received at the USB input. Our in-house team has programmed the XMOS firmware to optimise sound quality and ensure a perfect partnership with the GO bar‘s 32-bit Cirrus Logic DAC chipset.

A customised digital filter minimises pre-echoes and ringing artefacts. Our GMT (Global Master Timing) precision clock system ensures ultra-low jitter.

  • Ultra-res PCM up to 32-bit/384kHz via USB 
  • Native playback up to DSD256
  • 2x DXD
  • Full MQA decoding

Suits you, sir

Four bespoke digital filtering options:

  • Bit Perfect​ – no digital filtering, no pre or post ringing​
  • Standard – modest filtering, modest pre and posting ringing​
  • Minimum Phase​ – slow roll-off, minimum pre and post ringing​
  • Gibbs Transient Optimised minimum filtering, no pre-ringing and minimum post ringing​

​Two analogue processing modes:

  • XBass+  – an analogue bass boost to ‘add back’ lost bass response for more accurate reproduction of the original
  • XSpace  – a holographic sound field to open up your music to give you the spaciousness of a live concert

External affairs

The GO bar’s smart alloy case sports physical buttons for precise volume adjustment plus controls to select between various sonic tuning options. A column of coloured LEDs provides a handy guide to the format and sample rate of the digital audio currently playing, and whether XBass+ and/or XSpace are engaged.

At one end is an asynchronous USB-C input and at the other a pair of headphone outputs.

  • 4.4mm fully balanced output – headphones with a balanced cable/connector can benefit from the fully balanced circuitry of the GO bar
  • 3.5mm S-Balanced output – our S-Balanced tech cuts crosstalk and noise by 50% with regular single-ended headphones.

Balance of power

Despite its diminutive size, the GO bar’s analogue circuitry sports a balanced circuit design with symmetrical twin-channel output stage. This reduces noise and crosstalk in the signal path by fully separating the left and right channels. This is usually found in larger and more expensive amplifiers.

The circuitry is packed full of high quality discrete components and special attention has been paid to power supply filtering too, dramatically reducing signal noise introduced through the USB input.

Purity and power

The amp’s design combines sonic purity with power.

  • 475mW into 32 ohms​
  • 7.5V into 600 ohms

​No headphone amp of such a diminutive size can match the GO bar’s ability to drive tricky headphone loads or work with a wider variety of headphones.

The GO bar also incorporates two power tuning technologies:

  • iEMatch – attenuates power to suit high-sensitivity headphones and IEMs, it removes background noise and increases usable volume range
  • Turbo – ramps up the gain by 6dB to satisfy more power-hungry headphones

*Please note that the GO bar may not work with iPhones up to and including 6S when the phone battery is low (<30%).

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.

Gain

Gain is the amount of increase in audio signal strength. Gain is often expressed in decibels (dB).

The XMOS 16-Core chip processes the audio data received via the USB digital input.

This new low-latency XMOS microcontroller has greatly enhanced processing power. Compared to the current generation of eight-core chips, this new 16-core IC delivers double the clock speed (2000MIPS) and four times the memory (512KB), as well as the latest SuperSpeed USB standard.

iFi’s in-house digital development team has programmed the XMOS firmware to optimise sound quality and ensure a perfect partnership with the 32-bit Cirrus Logic DAC chipset used in the GO bar.

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 GO bar adopts MQA technology to receive and decode MQA audio and provide master-level sound.

Visit mqa.co.uk for more information.

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.

The GO bar’s analogue circuitry features balanced design with a symmetrical twin-channel output stage.

This topology, usually reserved for larger and more expensive amplifiers owing to its cost and complexity, reduces noise and crosstalk in the signal path by fully separating the left and right channels.

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.

Tantalum capacitors are another example of the top-notch components we prefer. These polarised electrolytic capacitors have superior frequency and stability characteristics, giving them a super high volumetric efficiency.

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.

Best Portable DAC/Amp Dongle 2022 from Headfonics

“The standout points are all skin deep and heard but not seen. Tonality, color, body, raw power plus one of the best imaging capabilities we were able to extract from all the dongle DACs that crossed our hands make the iFi Audio GO bar probably one of the best dongles we have reviewed in 2022.”

“THE DAD” OF THE DONGLE DACS

“THE DAD” OF THE DONGLE DACS HAS ARRIVED: THE IFI AUDIO GO BAR. It is a device that has a bestial technological capacity. It’s Incredible that such a small thing has so much power to decode any digital files, even MQA. I would pay double to have this power that I think will take a long time to overcome. I consider it a reference dongle DAC”

“one of the best I have tried so far”

“The iFi Go Bar delivers power, reliability, support of almost every digital format, solid industrial design, and excellent sound quality. The price is certainly high but it is one of the best I have tried so far and I suspect a product that is going to make waves in the category considering the company behind it.”

Ready, Steady, Go, GO Bar, Go! An Uber Headphone Amp in Your Pocket

“I am firmly convinced me that, yet again, iFi has another winner with its ultimately totable, hi-fi in your pocket, USB DAC/headphone amplifier that comes with its own volume control. Frankly, to me it’s a no-brainer.”

GO bar given the T3 Platinum Award

“As a basis for its overall performance, the Go Bar creates a much deeper, much wider and much taller soundstage for the elements of a recording to exist on. Compared to even the best-sounding smartphones, the iFi creates a far better defined stage – and it locks every strand of a recording on there with real certainty, meaning each element is secure in its own space and doesn’t impact on any other.”

One of the most advanced dongles on the market!

“The GO Bar is without a doubt one of the most advanced dongles on the market, full of functions and with a careful aesthetic. The declared power figures place it at the top compared to direct competition, which on the other hand and in general, play with the advantage of more contained prices.
If you were thinking of going for an iFi Gryphon, or a Mojo 2 and you are only going to use iems, the GO Bar is almost a must to consider, or at least it is worth listening to before deciding which one to buy. A great bet from iFi that sets the bar high for products of the same class.”

It lacks absolutely nothing, while having everything in the right proportions.

“The sound is incredibly rich with performance coming perilously close to larger DAC/amps with built-in battery and much more advanced circuitry.

The GO bar has perhaps the most organic sound characteristics we’ve heard so far from a device of its kind, the timbre of the sound is uniquely analog textured and very real while it’s almost impossible to find any trace of a digital footprint no matter how hard you look. At the same time, it does not lack at all in length, balance, detail and everything else we tend to define as superior technical ability.”

9 out of 10 from Android Police!

“When audio has this much clarity, you don’t just hear every subtlety of the music; you can also sense the size of the room it was recorded in. This feeling of almost being in the room while the song is being recorded is one of my favorite parts of critical listening, and it’s easily done with either jack on the GO bar.”

“…little block of wonderment…”

“While iFi’s GO bar might not shout its hi-res credentials, this little block of wonderment certainly seems to have it where it counts. While it might be pricier than some of its apparent competition when you start lining up spec sheets this highly-portable slab of tech starts to leave a clear gap between it and the usual suspects.”

Thanks to Jay for this detailed review.

Highly recommended by Trusted Reviews!

“It’s utterly agnostic, too. No matter if you feed in a poverty-spec MP3 file from Spotify’s free tier or an enormous DSD256 file from a device’s internal memory, the iFi rolls its sleeves up and sets about making the best of it. And when it’s given the right stuff to work with (anything that’s a step on from Spotify’s free tier, basically), the influence it can bring to bear can be profound.”

Unifying, freeing, and fun

“Versatility is the name of the game for the Go Bar and that makes it easy to use as a daily carry. The ability to connect any headphone or IEM I’d like has been freeing. I know I can slide it into my pocket, connect it to any PC, smartphone, or tablet and that it will work and deliver the same excellent sound quality across every device. It’s unifying, freeing, and fun.”

Reliable, well-built and well-operating units.

Overall the GO Bar is excellent and gets the job done, and I liked the fact that it has a neutral character in it, letting your connected IEMs/HPs shine through with their flavours. Also, it can blend in with different genres/recordings. If a particular recording is dynamic sounding, you’ll get that dynamism from the GO Bar. If the song is relaxed and laid back, you’ll hear it just as it is. This is a very good trait if you like neutral sounds.”

“Gold Bar is better than both units, sounding more musical with better tonality and harmonics. It has the largest sound-stage I’ve heard from a dongle, and excellent bass texture together with smooth midrange, and well-extended treble.”

I don’t know what ifi audio or any other manufacturer could do even better!

“The GO Bar lives up to its name and is immediately understandable, especially with the limited edition in gold. This small cable DAC/KHV in bar design is really an eye-catcher. Great workmanship and technically impressive, the GO Bar not only offers an attractive design but also an excellent sound experience.” (translated)

5 stars from Colin Aitkens on Head-Fi!

Thank you Colin for your review! Here is a snippet..

“The musicality of this dongle is the element that impresses me the most, every other dongle I’ve tried or owned has had good aspects but none has matched the musicality of this, or the detail. The Go bar never gets fatiguing when listening for extended periods, I used to struggle with dongles like the cobalt which seemed to pierce my ears after a couple of hours, not so with the Go Bar. It’s like velvet over long periods of use.”

Not your regular diet bar

Thank you to Head-Fi for this wonderful review!

“The iFi Go bars, both regular and anniversary, are not your regular diet snacks.
They are rather a high nutritional value whole meal that will satisfy the appetite of the most hungry listener by filling his senses with top quality music while keeping him healthy as the only real side effect is the increased power consumption.”

Changes the game

While it’s just a touch larger than the competition, there is no other USB DAC/Amp in the ultra-portable category with the same power, features, and refined sound quality. As a result, this product, which is about the size of a pack of gum, can competently drive flagship headphones, a fact that changes the game.

Thoroughly impressed

You know that little pocket on the front of your jeans? I’m not really sure what they’re supposed to be for, but I reckon you’ll definitely want to slip a GO bar in them after listening to one. The GO bar is the best-realised form of the “dongle” DAC/amp that I’ve had the chance to spend some proper listening time with, and while it’s easy to be initially skeptical with a device this size, I can wholeheartedly say that I’m thoroughly impressed. With its great DAC, IEM-focused features, plus ample power for dealing with high-impedance headphones, it’s a genuine audiophile option for all kinds of headphones if sheer portability is high on your list.
