GO blu. Go beyond.

With its lightweight, soft-touch polymer enclosure (great for Bluetooth reception, unlike signal-blocking metal), copper-coloured trim and ChronoDial watch crown-style control, the GO blu is a pleasure to use wherever you go.

iFi has even incorporated a high-quality chip-based (CMOS-MEMS) microphone, enabling hands-free calls, voice chat for gaming and access to voice assistants such as Apple Siri and Google Assistant.

Further flexibility is provided by the USB-C charging port, which doubles as an audio input enabling USB connection from source devices that don’t offer Bluetooth connectivity. Hi-res PCM audio data up to24-bit/96kHz is supported when the GO blu is connected in this way.

HD Bluetooth 5.1

The way iFi implements Bluetooth is anything but ‘run of the mill’ and despite its diminutive size the GO blu is no exception.

The use of Qualcomm’s latest four-core QCC5100 Bluetooth processing chip ensures that every current high-definition Bluetooth audio format is supported.

  • aptX Adaptive and aptX HD
  • regular aptX and aptX Low Latency
  • AAC
  • SBC (plain vanilla Bluetooth)


This means that every possible source device is handled at the highest audio resolution its Bluetooth specification allows – no other pocket-size DAC/amp delivers such comprehensive codec support, or such high-quality sound over Bluetooth.

The GO blu is Bluetooth v5.1-compliant, ensuring the best possible range, stability and performance, and its ‘Bluetooth engine’ can be updated over the air.

Three Unique Stages - Bluetooth. DAC. Amplifier.

Most pocket-size Bluetooth DAC/headphone amps incorporate all-in-one ‘system on a chip’ solutions to deliver input processing, digital-to-analogue signal conversion and amplification. These are simple and cost-effective, but they cannot compare with expertly designed, individually optimised circuit stages when it comes to sound quality.

Uniquely for a device of this type and size, the GO blu’s clever design packs in separate Bluetooth, DAC and amp stages, each engineered in distinct blocks to deliver the ideal combination of cutting-edge specification and superb sound.

The Bluetooth stage makes full use of Qualcomm’s latest four-core QCC5100 Bluetooth chip and supports every current high definition format.

This then feeds the DAC stage with a Cirrus Logic 32-bit DAC chip at its heart. This is coupled with a customised digital filter to minimise pre-echoes and ringing artefacts, and a precision clock system to ensure ultra-low jitter, thus reducing errors and distortion in the digital audio signal.

The amp circuitry benefits from symmetrical twin-mono signal paths and utilises iFi’s Direct Drive design concept – direct-coupled to ensure a clean signal path without distortion-inducing output coupling capacitors. The amp stage delivers up to 5.6V – considerably more power than other similarly sized devices – handling even relatively tough headphone loads with ease. To ensure signal strength suits the sensitivity of the connected headphones or earphones, auto-gain adjusts output up or down by 6dB.

Dual-Mono circuit for superb staging

Featuring a dual-mono circuit design, the Go blu dedicates a separate channel to left and right signals. With each channel receiving a dedicated signal path, you get superior separation between the channels with reduced distortion and a more ‘holographic’ sound quality.

USB-C for charging and output

The handy USB-C port provides twin functions. Use it to recharge the built-in batteries once the 10-hour battery life has expired. It also outputs a digital signal at up to 24 bit/96kHz, making this ideal as a high quality Bluetooth DAC for connecting to your AV, hi-fi or speaker system (with compatible USB input).

XBass and XSpace sound programmes

XBass and XSpace settings tailor the sound to suit your taste and music. XBass gives an analogue bass boost, enhancing low frequencies without muddying the mid-range. XSpace analogue headphone spatialiser enhances the sound for a more spacious and enveloping sound.
