GO link from iFi audio - the headphone dongle linking you with your music. Its purpose is twofold. First, to enable corded headphones and earphones to connect to digital devices that don’t have a 3.5mm headphone output. Second, even if a device does have a headphone socket, the GO link delivers a big sonic upgrade. This is because its sophisticated DAC (Digital-to-Analogue Converter) and headphone amp circuitry is superior to the audio tech contained within mobile devices and computers.
At one end of the GO link is a USB-C connector, at the other is the DAC and headphone amp circuitry, both housed in robust yet lightweight magnesium alloy enclosures. In between is a 6cm length of flexible cable – this aids practicality, allowing the DAC/amp section to be angled towards the listener and reducing stress on the USB port to which the GO link is connected.
Superior sound with a twist.
HIGHLY ADVANCED DAC
Rarely implemented high-end features such as adjustable analogue gain with DRE (Dynamic Range Enhancement) plus technologies to minimise THD (Total Harmonic Distortion) and crosstalk are possible due to the DAC chip’s advanced specification.
DAC’S THE TICKET
At the heart of the GO link lies a power-efficient, high-performance DAC chip from ESS Technology’s Sabre HiFi series – the ES9219MQ/Q – benefiting from 32-bit HyperStream III architecture. This combines with Quad DAC+ and Time Domain Jitter Eliminator technologies, plus our dedicated clock circuitry utilising a specialised crystal oscillator, to deliver ultra-low distortion, excellent clarity and impressive dynamic range.
DO THE TWIST
The cable linking both sections together uses silver-plated copper conductors with individual polymer insulation in a ‘twisted pair’ configuration. This rotational twist helps to optimise inductance and capacitance and also aids noise rejection. The GO link’s sound isn’t affected by electromagnetic interference picked up from nearby electrical sources.
MOVE WITH THE MUSIC
Unlike other headphone dongles, the GO link doesn’t rely on the software-based volume controls in connected digital devices. This can adversely affect audio resolution. Instead, adjusting the volume on the connected device controls the volume level in the GO link’s DAC, not in the phone, tablet or computer. This hardware-based volume control is another feature that helps to deliver the GO link’s superior sonic performance.
HEADPHONE HEAVEN
The GO link’s headphone amp feeds a gold-plated 3.5mm socket, incorporating our S-Balanced configuration to reduce noise and crosstalk. It delivers a power output of 70mW into 32 ohms, and a maximum voltage output of 2.05V into 600 ohms. This gives it plenty of oomph to drive the kind of headphones and earphones likely to be used with the GO link and easily outclasses the headphone outputs built into smart devices and computers.
HI-RES IN GLORIOUS COLOUR
The GO link’s hi-res audio credentials are highly impressive given its diminutive size and price tag. An LED changes colour to indicate the incoming audio format – PCM, DSD or MQA – and the PCM/DSD sample rate (PCM to 32-bit/384kHz, DSD to 11.2MHz (DSD256) and MQA).
Not owning bluetooth headphones, and I like my sennheiser HD560S's, I was looking for a connection for a smartphone and happened across this device. Having read the sales pitch and some of the reviews, I thought,'Why not?'. It arrived swiftly. I plugged it in and was so unimpressed, but decided to persevere as a lot of the reviews had pretty much started off the same way. It was always plugged into the phone for my music and films, until after about a couple of months use, I left it at home. No biggie, as I could use the headphone jack (Galaxy a71). After about ten minutes of messing about with sound settings, I realised there was nothing wrong with the settings on the phone.. it was my ears that had been so used to hearing how clear and crisp the music had been with this adapter. The difference after taking it away, if not measurable by machine, is certainly measurable by ear. Even this sceptic is well impressed. The device hasnt even made it to the intended phone, as after hearing the difference there is no way I am going back to the original headphone jack, as good as it was because this is better. It's nicely made, and although it looks deceptively fragile, in my hammer hands, surprisingly, it certainly isn't. I personally think it is an elegant piece of kit, with both ends of the connections a snug fit, and I'm pretty sure were it long enough, you could tow a car with the braided cable.. please, don't try this. If you know someone who has one, and they'll let you have it, give it back after just a month of continuous use and then see how long it takes you to figure out what's wrong with your phone settings. If you have a device with a headphone socket and a USB c port, this is such an upgrade to your listening experience. Even a chimp like me can hear it, and the ears dont lie. In the future, you may even buy a different adapter, but after using this one, you will never go back to the headphone jack. I'm glad I bought this before buying something similar. Well worth the money.
I bought this for listening to hi res music (jazz and classical), streamed from Qobuz mostly, on my Motorola Edge 20 pro phone. I use two sets of headphones: a Shivr wired/bluetooth set and a pair of Beyerdynamic DT 990 pro. My ears, half way through their seventh decade, struggle to tell the difference with the Shivr (which are actually pretty good phones IMHO). The 250 ohm impedance Beyers need the pre-amp to hear much and sound fantastic through the Go Link. Can I hear the DAC benefit? I'm not entirely sure, but I like the product a lot as a pre-amp at this price.
Was looking at wireless earphones having changed to a phone with no headphone jack, and I was not happy with quality of generic C to Jack connectors but helpful advice suggested this product. Way better sound and volume, and no need to move to wireless.
Not sure why ,but get occasional interference.
Doesn't happen with standard USB c to headphone Jack.
