Specifications and features
Overview
The iFi Audio GO Blu is a compact portable DAC/amplifier designed to deliver high-quality audio on the go. With its advanced Bluetooth connectivity and audiophile-grade performance, this device ensures precise sound for music enthusiasts.
Pocket-Sized Design for Total Freedom
The GO Blu stands out with its ultra-compact and lightweight design, perfect for portable use. Its small dimensions and featherweight build make it easy to slip into a pocket or bag without adding bulk. The polymer casing provides a comfortable grip while optimizing Bluetooth reception, unlike metal, which can block signals.
The device features an elegant design with copper accents and a control dial inspired by luxury watches. This multifunctional “ChronoDial” allows intuitive volume adjustment and playback control. All controls are designed for blind operation, ideal for use on the move.
Cutting-Edge Wireless Connectivity
At the heart of the GO Blu is a Qualcomm QCC5100 Bluetooth 5.1 quad-core controller. This next-generation chip ensures a stable, high-quality connection with smartphones, tablets, and computers.
The GO Blu supports a wide range of Bluetooth codecs, from common ones (SBC, AAC) to advanced options (aptX, aptX HD, aptX Adaptive, LDAC). This extensive compatibility allows for lossless audio transmission with compatible devices. The aptX Low Latency codec is also included for perfectly synchronized audio and video.
Hi-Res Audio Wireless certified, the GO Blu guarantees faithful reproduction of high-resolution audio files via Bluetooth. For purists, a wired USB-C connection is also available, supporting PCM streams up to 24-bit / 96 kHz.
High-Performance Audio
Despite its small size, the GO Blu is packed with high-end audio components. At its core is a 32-bit Cirrus Logic CS43131 DAC, renowned for its performance. It is paired with a proprietary digital filter that reduces distortion and artifacts.
The amplification stage uses a dual-mono balanced architecture and iFi’s Direct Drive technology. This design ensures an ultra-pure signal path, free from coupling capacitors that can introduce distortion. The output power reaches 5.6V, effectively driving most headphones on the market.
The GO Blu also features a precision clock system that minimizes jitter, ensuring smoother and more accurate playback. Automatic gain adjustment optimizes output based on the sensitivity of the connected headphones.
Versatility at Its Best
The GO Blu excels in versatility. It offers two headphone outputs: a 3.5mm single-ended jack and a 4.4mm balanced Pentaconn output. The latter delivers superior channel separation and signal-to-noise ratio.
The device includes a high-quality CMOS-MEMS microphone, enabling hands-free calls, voice chats for gaming, or use with voice assistants like Siri or Google Assistant.
Two sound enhancement modes are available: XBass to boost low frequencies and XSpace to expand the soundstage. These effects can be activated individually or combined to suit listening preferences.
Comfortable Battery Life for On-the-Go Use
Despite its high performance, the GO Blu offers a comfortable battery life of approximately 10 hours with Bluetooth use. The battery charges via the USB-C port, which also supports wired audio connections.
An intelligent charging system allows the device to be used while charging. In this mode, the battery charges up to 80% to preserve its longevity.
