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.
