iFi's Go blu Air DAC packs big performance in a pocket-sized form - Yanko Design
"Audiophiles are constantly in search of the endgame gear that redefines their listening experience. A DAC is one essential accessory all music lovers swear by to listen to audio from their Hi-Fi headphones, IEMs, or earphones. There's no shortage of digital-to-analog converters in the market, with iFi being one of the most trusted brands. Their Go pod and Go Blu have stood the test of time, and now it has a worthy successor to the latter that could be game-changing."
"The GO blu Air Bluetooth headphone amplifier is designed to be lightweight at just 30 grams and portable enough, measuring just 5 cm tall. That makes it ultra pocketable without compromising on the audio performance, akin to a Hi-Fi audio accessory that can amplify a range of high-end wired headphones or IEMs, given its 256mW power. The size of the DAC is commendable even by their own standards achieved in the past."
The GO blu Air Bluetooth headphone amplifier weighs 30 grams and measures roughly 5 cm tall, making it highly pocketable without sacrificing audio performance. It delivers up to 256mW, suitable for amplifying high-end wired headphones and IEMs via 3.5 mm (with anti-crosstalk) and balanced 4.4 mm outputs. A three-stage processing chain optimizes sound across codecs. An integrated MEMS microphone with noise cancelling supports calls and voice assistant use. The architecture separates DAC and amplification stages to minimize distortion and noise. Bluetooth connectivity uses the Qualcomm QCC5144 chipset with Bluetooth 5.2 and support for LDAC, LHDC/HWA, aptX Adaptive, aptX HD, aptX, AAC, and SBC. The heart of the unit is the Cirrus Logic MasterHIFI DAC chip.
