iFi GO blu
#1 in Portable/Bluetooth Amplifiers · Rated 4.5
Ultra-compact Bluetooth DAC/amp with dual outputs
The GO blu is a pocket-sized, hi-fi oriented Bluetooth DAC/amp from iFi Audio. Built around a dedicated DAC and amp stages, it delivers wired-like detail over Bluetooth with a compact, clip-on form factor. It supports LDAC, aptX HD, and AAC, and provides both 3.5mm SE and 4.4mm balanced outputs for flexible headphone pairing. The unit is designed for audiophiles who want high-resolution wireless listening on the go, with a dual-mono output and hardware-based XBass/XSpace enhancements. It integrates with a broad ecosystem (Android, iOS, Windows, macOS) via Bluetooth and USB digital audio paths, and can be used with a wide range of headphones, including sensitive IEMs and lower-impedance cans. The GO blu stands out for combining robust codec support with a compact chassis and dedicated DAC/AMP paths rather than relying on a single-ASIC approach. Suitable for portable users who want high fidelity without cables, and for those who value a tactile control experience.
