iFi Audio's hotly-anticipated GO pod turns your prized wired earphones wireless! These Bluetooth adapters fill a niche to make your flagships even more convenient, and better sounding than before. Stock arrives end-July 2023. Never has Bluetooth promised to be this flexible and high-quality. From the makers of the acclaimed GO blu comes wearable Bluetooth DAC/headphone amps that you can attach to MMCX and 2-pin IEMs – dispensing with those messy cables in the process.  And praise has been pouring in for iFi. Headfonia place GO pod on their Recommended Buys list. Headfonics found it wanting for nothing. GO pod gets highly recommended on Ear Fidelity. And John Grandberg writes "nobody else has so far managed to execute the idea to such a high standard" on Darko.Audio. Twister6 compares them to wired sound quality. [See Product Desc. For More] iFi's headline act is how GO pod is the first device in the world to support Hi-Res transmission of 24/96kHz audio, with LDAC, Qualcomm® aptX™ Adaptive and Snapdragon Sound codecs built on the Bluetooth 5.2 standard. That's possible with iFi separating the Bluetooth receiver, DAC and amp modules even in the featherweight, space-limited GO pods.  Qualcomm’s top-tier QCC5144 receiver maxes out Bluetooth quality, and that data stream gets sent to a separate Cirrus Logic CS43131 DAC for no-compromise decoding.  It's not just about the GO pod's fidelity, but also its ability to deliver that signal as pristinely as possible into IEM impedances that have been steadily dropping. Despite its miniature battery power supply, this iFi is rated into loads as low as 16ohms – right after USB DAC/amp dongles, GO pod is the very next credible DAP replacement. Indeed, Bluetooth just got serious. Naturally you'd want to get these attached to as many as your prized IEMs as possible. And in addition to stock MMCX and 2-pin attachments, Pentaconn Ear, T2 IPX and A2DC GO pod connectors are sold separately.  Even GO pod's charging case reeks of iFi's attention to detail. With each storage compartment roomy enough to accommodate the largest CIEMs, there's also a 1,500mAh battery that's large enough to offer up to 35 hours of play time.

Furthermore, iFi's analog volume control consistently maintains a superior signal-to-noise ratio at all listening levels, surpassing conventional digital controls.  The third evolution of iFi's portable powerhouse also reaches a new peak in parts quality. It now incorporates new metal film resistors in the analog stage, and the decoding process, powered by a trademark Burr-Brown DAC, achieves even greater precision thanks to a new low phase noise crystal oscillator. Indeed, hip-dac 3 provides a remarkable taste of high-end audio. Explore the rest of iFi's innovations here, or browse our collection of DACs and amplifiers for more options here.

iFi Audio's work with ESS Technology DACs continue, with balanced. GO Link Max, their latest balanced 4.4mm dongle, runs with dual ES9219C chips.  What's special about the ES9219C is that it grants GO Link access to its on-chip analog volume control. This dongle attenuates volume in the analog domain granting much better signal-to-noise performance than the average competitor's lossy digital volume control. It receives a full 5⭐ from What Hi-Fi?. Music player levels of detail and fidelity even from USB's 5 volt supply are possible with GO Link Max. A thoroughly regulated circuit and clean power form the basics here, as with every iFi. [See Product Desc. For More] After decoding, iFi's generous use of negative feedback quashes distortion and claims huge signal-to-noise ratio – aided by the analog volume controls of its ES9219Cs. Powerful op-amp output buffers can supply high power and mean iFi's little wonder promises high damping factor while maintaining its low distortion into low impedances typical of IEMs, Focals, Fostexs and Rosson Audio Designs. Still the closed-loop internal gain remaining after the application of negative feedback around GO Link Max's op-amp IC analog circuit remains high. So where she really shines is in swinging voltage, opening up the sound of any high-impedance Audio-Technica, Sennheiser and ZMF Headphones while barely breaking sweat. The quality of GO Link Max's signal will translate to nearly everything you choose to drive from its balanced 4.4mm output. Flying the dongle DAC/amp flag high is GO Link Max, till you turn to iFi's other upgrades here, or others in our catalogue here.

The headline of BTC-2 might be its Bluetooth 5.1 LDAC, aptX™ HD and aptX™ Low Latency wireless inputs and outputs, but that doesn't quite cover all the functions that Cayin Audio's new desktop hub offers.

iFi Audio's newest Zen CAN 3 puts flagship technology into an affordable 4.4mm balanced amplifier, merging futuristic xMEMS capability with good old school Class A. Even as we wait on xMEMS to achieve widespread availability, there's so much for the budding audiophile to enjoy with Zen CAN 3. It's a versatile little beast to Headfonia. Its maximum power output of 2 whole discrete Class A watts on balanced 4.4mm promises to drive your cans to their maximum potential. [See Product Desc. For More] What is even more impressive about Zen CAN 3, though, is its practicality for listeners of entry-level headphones, right up to easy-to-drive Focal and IEM flagships. iFi's use of their custom 'Operationsverstärker' op-amps means that they're fully in charge of how much – or importantly, how little – gain is applied internally to Zen CAN 3. This mini marvel is capable of working at unity gain at the push of a button. With 0dB of gain applied to the incoming signal, Zen CAN 3 is realistically able to drive 90 per cent of transducers out there, from the easiest to the most difficult, without suffering any noise penalty. It's unlikely users will ever find it necessary to go beyond unity gain on their iFi, allowing listeners to climb up their knob where signal-to-noise can reach a leading 125dB, while always enjoying perfect channel balance. Zen CAN 3's flexibility doesn't stop there. With built-in 'Movie' and 'Gain' modes on top of favourites like XBass and XSpace, all implemented in the analog domain without lossy digital EQ, iFi owners can tweak the Zen CAN 3 to their exact liking. Feed Zen CAN 3 signal from iFi's own Zen DAC 3 and Zen Blue 3, or take hip-dac 3 on the go as you explore the rest of their range here.

Given light energy is the only way to completely isolate a system galvanically, with no electric potential between points, iFi Audio's LAN iPurifier Pro input is a class above other network filters. LAN iPurifier Pro yields major improvements as a result, reducing noise and jitter by counting itself as the only other mainstream digital audio network accessory apart from Sonore to feature an optical LAN input.

A perfect solution for consumers who wish to stream music via their DAC without streaming support.  Complete with box and in full working condition, the only item missing is the ethernet cable. Warranty Provided: One year from the date of purchase. 

Below iDSD Diablo 2's futuristic exterior and the promise of new, wonderful technologies like xMEMS and wireless Bluetooth 5.4 aptX™ Lossless input is a tried-and-true iFi Audio product that is ready to deliver – today. The heights the proven platform that was the original iDSD Diablo gets taken to the rafters with its further optimised circuit and boutique parts overflowing from Diablo 2's red, race car chassis. [See Product Desc. For More] iFi's usual custom operational amplifiers show up here in a design that boasts more careful application of local negative feedback, rather than the more standard global variety. By using sparing error correction, iDSD Diablo 2 veers from the glare and harshness of cheaper solid-state designs caused by transient intermodulation distortion, with the signal from its Burr-Brown DAC still being clean and precise throughout. Purewave, the name coined for the direct-coupled analogue circuit developed for iFi by Hi-Fi and Parasound legend John Curl, ensures a fully balanced, differential signal path produces minimal distortion and up to 120 dB of signal-to-noise ratio.  Such performance is possible also due a high 15 volt operating voltage – a number much more akin to desktop amplifiers – that expands headroom and circuit linearity in tandem with Diablo 2's local, carefully applied, negative feedback. That precision gets backed by even more power: nearly five watts stands ready to drive any headphone load, including a HEDDphone 2. Accessorisation fitting for the premium status of this red arrow is included, not least a carrying pouch that'll accomodate iFi's low-noise iPower DC charger and a 4.4mm balanced line-out cable to dual XLR cables, to feed a desktop amplifier.

The overachieving ZEN Stream was just the beginning for iFi Audio. Their NEO Stream digital audio streamer does it all – digital and analog outputs, with the one-of-a-kind advantage provided by iFi’s optical LAN input. iFi's new streaming hub counts itself as the only other mainstream digital audio streamer apart from Sonore to feature an optical LAN input. Stereophile writes "NEO Stream punches way above its retail price, bringing complex high-end audio down to earth". Headfonics raved about it. Given light energy is the only way to completely isolate a system galvanically, with no electric potential between points, NEO Stream's optical LAN input is a class above its peers, and indeed punches way above its weight. Indeed, you can confidently insert the NEO Stream into nearly any high-end, top-dollar system, knowing it will perform admirably without hindering flagship DACs from manufacturers like Denafrips, Holo Audio, or Matrix Audio. [See Product Desc. For More] The I2S and AES/EBU outputs around back effortlessly transmit digital signals to your system through iFi's Roon Ready and Signalyst HQPlayer NAA modes. Alternatively, you can bypass a downstream DAC entirely and utilise the NEO Stream's balanced line output. But let's start at the source. NEO Stream includes an OptiBox and the relevant cables to connect to the gigabit ethernet output from your router. Once done, iFi's OptiBox hooks up to NEO Stream and acts as an intermediary to completely block parasitic noise from your home's modem with its galvanic isolation. Files up to DSD512 and PCM 768Khz are transmitted this way without bandwidth limitation. The transfer of digital data between NEO Stream and your DAC is regulated by iFi's GMT femto-precision clock and intelligent memory buffer. GMT ensures your digital transmission between router, NEO Stream and DAC stays jitter-free, with designer Thorsten Loesch describing it to 6Moons as "intelligently and dynamically controlling the clock that drives the DAC chips and streams data from the memory buffer ... not a secondary PLL ... entirely new concept that completely blocks jitter". NEO Stream isn't a run-of-the-mill streamer then, but rather applies iFi's proprietary technology and techniques to stand apart from others. Excellent phase-noise performance and low-jitter are key when transmitting I2S over HDMI, with the bit, master and word clocks derived more accurately than ever. This is particularly important when using one of Signalyst HQPlayer's oversampling reconstruction filters with a Denafrips or Holo Audio NOS DAC, as timing accuracy becomes crucial, and even minor variances can have a significant impact. NEO Stream is reflective of iFi's drive never to settle, coming up with original solutions at the digital input and output that makes these newcomers to streamers appear like veterans, delivering results not yet seen before at this price, availability or common use.

Like the best blast from the past, Ferrum Audio rekindle their Mytek Audio roots to produce Erco – a DAC and 4.4mm balanced headphone amplifier, with the star being an analog gain control pre-amp promising maximum transparency. Ferrum's know-how building Mytek Audio under the HEM label means they know how to extract the most from the renowned ES9028Pro from ESS Technology, even in the modern day. Airy, bathed in a beautiful light with delicate detail flowing around you either through headphones or speakers, Erco makes a case of working in any situation you expect in 2022. [See Product Desc. For More] Ferrum's proprietary work sees them leash Erco's current-output ES9028Pro to a 100Mhz master clock via PLL. This ESS workhorse turns DSP work over to an ARM MCU chip to work as a data master running its own slow roll-off minimum phase digital reconstruction filter, as well as all sorts of proprietary functions discussed. Ferrum's proprietary filter makes way for a Master Quality Authenticated (MQA) filter when such a stream is detected from Tidal Masters. More crucially, Erco's ARM MCU operates in tandem with the ALPS volume knob. Volume attenuation happens not only through signal level with a turn, but also adjusts internal analog gain via relays. This ensures Ferrum's volume control remains not only analog, but of the most transparent kind. The internal gain switching quashes noise by preserving signal at the ranges you're using Erco's pot at. Erco's MCU keeps you at the most transparent levels by intelligently dropping and increasing circuit gain as you really need. Erco makes the argument you won't need an external pre-amp post digital conversion into your stereo system. And this transparency is on full show plugged into its 4.4mm headphone output – capable of pushing 6 watts of balanced power. Integrated circuits from Analog Devices promise huge slew rates and 200Khz of closed-loop bandwidth to push your big headphones with nary a strain. Erco is Ferrum's promise – and a statement – that their single-box solution is ready to tackle nearly every task you have need for. Headfonia summed up that Ferrum have the perfect foil for Oor in Erco, with Headfonics citing the excellent headphone output power. Indeed, measurements from Hi-Fi News confirmed Ferrum's extra work payed off. Audiophilia implore you to approach this all-in-one with an open mind, and be blown away by a high value proposition. Hear how expanding upon Erco's compact talents could pay off by exploring the rest of Ferrum's range here, or view our other desktop devices here.

It's quite clear being named Oor (meaning 'ear') how Ferrum Audio intended their dedicated headphone amplifier to be enjoyed. Yet under the hood, there's so much to chew on from the collaborators of Mytek Audio's meteoric rise, about their compact overachieving flagship built to drive the best Head-Fi has to offer. Still we let the accolades judged by ear pour in from seasoned reviewers hailing EISA's Best Headphone Amplifier of 2022 supreme. It's on Headfonia's Recommended Buys list for a reason, and Headfonics were equally sweeping in their praise. [See Product Desc. For More] Oor was too fun for Soundnews who put Ferrum's upstart against the industry's top dogs. Even Hi-Fi-centric Part-Time Audiophile awarded it an Editors Choice, and Hi-Fi News an Outstanding Product award complete with measurements.  In Oor is the complete package. Ferrum managed to balance the demand for neutrality in a flagship source, with the deep, impactful bass of a DC-coupled design. The technical chops are on show throughout by the proudly Polish HEM, who built Mytek but know a thing or two about circuit design themselves.  Oor's business side of things – a power stage consisting of a discrete transistor op-amp designed from the ground up – remains inherently linear. Even before negative feedback is applied.  Excellent frequency response in the open-loop, without coupling capacitors in the signal path, allows excellent low-frequency performance guaranteeing tight bass. And high-frequency extension soars to 60Khz, before negative feedback took that out flat to 100Khz. Phase response in the human hearing range is stellar, for potent, precise and hard-hitting dynamics to show off your flagship headphones. READ ALSO The inside story designing Ferrum Oor Feedback is not of the ordinary variety either, with current feedback providing speed of the loop gain through the capacitance of solid-state transistors for low transient intermodulation and slew-induced distortion.  Ferrum make their good Oor great, meanwhile, biasing the transistors making up their proprietary power stage in novel manner. Sitting between a sliding bias Class A and high-bias Class AB output stage in definition, Oor achieves the best benefits of both – highly linear transistor operation, plus high efficiency and lower quiescent current and heat. Thus is 8 watts of power delivered into HIFIMAN's Susvara achieved. Oor gives you power in quantity as well as quality. Certainly the same thing can be said about the listener's level of enjoyment too, regardless of headphone. Take Oor up another notch with the addition of the HYPSOS power supply, browse all of Ferrum's products here, or view our other desktop devices here.

Ferrum Audio redefine DC linear power supplies with HYPSOS. Ordinarily, a box capable of outputting 30 volts and an instantaneous 9 amperes of current via DC barrel would automatically take the headlines. But that wasn't enough for Ferrum to stop at. Builders HEM – the hands behind Mytek Audio – started with a toroidal transformer taking power from AC but didn't stop there. They added their interpretation of filtered switch-mode power supplies and regulation for the ultimate hybrid. [See Product Desc. For More] READ ALSO How Ferrum redefined the linear power supply HYPSOS adopts the strengths of linear and SMPS to reduce voltage ripple, and lower noise plus EMI, by way of multiple levels of filtering.  This little box capable of putting out 80 watts of power into your DC-powered components will enhance their fidelity due to the raw quantity and quality of power. HYPSOS allows the user to tailor the required voltage to suit a pre-determined list of gear, or manually set custom parameters. A wide continuous ouput voltage range of 5 to 30 volts, with up to 6 amperes of current, can be delivered to the load. HYPSOS audibly improved the variety of components 6moons and Hi-Fi News tested.
