Manufacture Description
HD Bluetooth.
The GO blu uses the same Bluetooth 5.1 as seen in other recent iFi products. Furthermore, we have separated the modules so that every last drop of audio quality is unmatched.
AAC aptX aptX HD, aptX Adaptive, aptX Low-Latency LDAC & HWA/li> Bluetooth 5.1TM at 24/96kHz. And when you wish, just use the USB-C connection and enjoy High-Res USB audio too!
Max sonics. Free the Smartphone.
Traditional wireless headphones or earphones of any kind integrate Bluetooth processing, D/A conversion and amplification onto one, standard ‘off the shelf’ chip. There is a ceiling to the sound quality that can be achieved.
Team good corded headphones or in-ear monitors, with a separate, high-quality portable DAC/headphone amp, and your sound quality will beat any pair of wireless headphone or earphones hands down.
The GO blu means no compromise on sound quality.
Pair the GO blu to your Apple/Android. Connect your favourite corded headphones to the GO blu and then tuck it away – it’s so petite it will slip into your running gear or suit pocket. It’s also gorgeous enough to show off by leaving it on the table at your favourite coffee shop!
GO Balanced.
Whether you use balanced or non-balanced headphones, you get the least noise and best channel separation for the most enjoyable music.
The GO blu boasts a Pentaconn 4.4mm output enabling headphones equipped with balanced connectivity to take full advantage of the GO blu’s balanced amp design.
In addition, the 3.5mm output benefits from iFi’s proprietary S-Balanced circuitry. This cuts crosstalk and related distortion in half when used with regular, single-ended headphone connections, this is especially beneficial with high-sensitivity in-ear monitors.
Both outputs are gold-plated to resist tarnishing and thereby maintain optimum contact quality.
The balance of power.
Diminutive. Balanced. Powerful.
The Go blu amp circuitry benefits from symmetrical twin-mono signal paths and utilises iFi’s Direct Drive design concept. Plus it incorporates circuit components of a quality not commonly found in a device of this kind.
This means ultra-low distortion across the entire signal bandwidth. The sound is purer, clearer and more naturally expressive.
The amp stage delivers up to 5.6V, considerably more power than others. It handles tough headphone loads with ease. Auto-gain adjusts output up or down by 6dB to ensure signal strength suits the sensitivity of the connected headphones/earphones.
