About the iFi Go blu

Take high-quality sound anywhere you go

The Go blu is iFi's smallest DAC yet, but don't let its size deceive you — it's more than capable of providing powerful, detailed hi-fi sound on the go. This tiny DAC weighs less than a "AA" battery, but it can drive almost any wired headphones with ease. You don't even need to connect a USB cable between the DAC and your smartphone. It wirelessly connects to your phone via Bluetooth.

The Go blu is iFi's smallest DAC yet, but don't let its size deceive you — it's more than capable of providing powerful, detailed hi-fi sound on the go. This tiny DAC weighs less than a "AA" battery, but it can drive almost any wired headphones with ease. You don't even need to connect a USB cable between the DAC and your smartphone. It wirelessly connects to your phone via Bluetooth.

Eye-catching looks and thoughtful design

The Go blu's body is made of a soft-yet-durable polymer that doesn't interfere with Bluetooth signals like traditional metal enclosures do. The copper-colored trim adds a subtle touch of flair.

The side-mounted volume knob sports a knurled design that pays homage to the crowns of classic Swiss chronographs. It's precision-engineered from brass, steel, aluminum, and nickel and allows fine volume adjustments. The multifunction button, found in the center of the volume knob, is used for controlling music and activating voice assistants through your paired smartphone.
 

Go blu

The Go blu is small, but it can drive most headphones with ease.

High-quality Bluetooth

The Go Blu uses a potent Qualcomm Bluetooth 5.1 chip that supports all Bluetooth hi-fi formats, like aptX® Adaptive, aptX HD, LDAC, and more. The cool part about that? Every pairable audio source is reproduced at the highest possible resolution. The Go blu also has a built-in noise-canceling microphone for taking calls and accessing voice assistants.

Dedicated chips and optimized circuits

Some DACs use a single chip that combines their D-to-A converter, amplifier, and Bluetooth circuitry. By doing so, those DACs essentially cap the level of sound quality they can achieve. The Go blu uses three discrete chip stages rather than just a single multi-purpose chip, for higher-fidelity sound. The digital-to-analog converter chip, Bluetooth chip, and headphone amplifier chip are all separate and have their own respective, optimized circuits.

An advanced Cirrus Logic 43131 DAC chip handles the tricky switch from digital to analog. iFi paired the chip with a custom digital filter to fine-tune the sound to their high standards. It uses a precision clock to reduce jitter and distortion in the signal.

The headphone amplifier chip's left and right channels are laid out in a dual-mono configuration, meaning there are separate, symmetrical amp pathways for each channel. The company also employed their Direct Drive design concept to the amplifier circuit to ensure a clean, direct signal path to the headphone outputs. The amp stage delivers up to 5.6 volts of output — nearly double the power of most portable DACs.

Connections

You'll find a USB-C port on the bottom of the Go blu that acts as both a charging port as well as a wired input for non-Bluetooth sources. If you use the USB-C port as a source input, the connection supports sample rates up to 24-bit/96kHz PCM.  On top, there's a balanced 4.4mm Pentaconn output for compatible high-end headphones and a standard unbalanced 3.5mm headphone output. Both outs are gold-plated for optimum contact and signal strength.
