A design that leaves nothing to chance

With its lightweight soft-touch polymer chassis (ideal for Bluetooth reception, as opposed to metal, which attenuates the signal), copper coating and ChronoDial control wheel, the Go Blu is a pleasure to use.

iFi has even integrated a high-quality microphone based on a CMOS-MEMS chip, enabling hands-free calling and access to voice assistants such as Google Assistant or Apple Siri.

Additional flexibility is provided by the USB-C charging port, which doubles as an audio input allowing USB connection from source devices that don't offer Bluetooth connectivity. Connected in this way, the Go Blu supports audio streams up to PCM 24bit 96kHz.

Bluetooth 5.1

The Go Blu uses a latest generation Qualcomm QCC5100 4-core chip for its Bluetooth 5.1 connectivity, ensuring that all current high definition codecs are supported. Thus, the Go Blu supports aptX Adaptive and aptX HD, LDAC and HWA/LHDC, as well as the classic aptX and aptX LL codecs. In addition, the Go Blu is Bluetooth 5.1 compliant, ensuring optimal range, stability and performance.

Three independent stages

Most portable Bluetooth headphone DACs/amplifiers incorporate all-in-one hardware solutions for input processing, digital signal conversion and amplification. These solutions are simple and affordable, but are not comparable to individually designed and optimized circuitry stages.

Thus, the Go Blu benefits from an intelligent design, separating the Bluetooth, DAC and amplifier stages on independent circuits to achieve the best possible performance.

Thus, the Bluetooth stage provides the DAC, based on a 32bit Cirrus Logic chip, with a digital signal. This chip is coupled with a custom digital filter to attenuate potential sound artifacts, as well as a clock system to ensure ultra-low jitter and reduce distortion.

The amplifier stage benefits from balanced dual-mono circuits and uses iFi Audio's Direct Drive technology. This allows for direct coupling to ensure a clean signal path, without coupling capacitors that can generate distortion. The amplifier stage can deliver up to 5.6V and is capable of handling high impedance headphones. In addition, to ensure that the signal strength is matched to the sensitivity of the connected headphones or earphones, the automatic gain adjusts the output by +/-6dB.

A multi-function button with incredible precision

The Go Blu ChronoDial is a masterpiece of incredible precision in design. It offers precise analog volume control. It is multi-functional and can also control playback and even activate the voice assistant of a Bluetooth connected device. This ChronoDial is made up as follows:

  1. Brass supporting column with anti-corrosion
  2. Brass locking nut with anti-corrosion
  3. Precision 304 stainless steel bearing
  4. 304 stainless steel main dial with beryllium cobalt copper coating
  5. High-purity nickel push-button spring
  6. Precision CNC machined AL6063 aluminum push-button

Balanced & Single-ended

Whether you use balanced or single-ended headphones, the Go Blu provides very low noise and excellent channel separation.

It has a Pentaconn 4.4mm output allowing headphones with balanced connections to take full advantage of the Go Blu balanced amplifier design.

In addition, the 3.5mm jack output features the brand's exclusive S-Balanced circuitry. This circuit halves crosstalk and associated distortion when used as a single-ended output, which is particularly useful for high-sensitivity in-ear monitors.

Cirrus Logic CS43131 DAC

The digital to analog conversion stage of the Go Blu is based on a powerful 32bit Cirrus Logic CS43131 chip. It offers a dynamic range of 130dB and a THD+N of -115dB.

XBass and XSpace technologies

Thanks to XBass technology, which restores dynamic low frequencies, and XSpace technology, which expands the soundstage, the Go Blu demonstrates great musicality.
