GO bar, iFi's premium pocket-sized USB DAC Small but Powerful, has arrived!

The top-of-the-line USB model in iFi's GO series of ultraportable DAC/Headphone Amplifiers, the small but mighty GO bar is the world's most powerful headphone amplifier of its size.

iFi's acclaimed DAC/headphone amplifiers have formed the foundation of the company's product lineup since its inception in 2012, bringing brilliant sound to smartphones, tablets, PCs, Macs and more. Last year, iFi introduced the GO blu, the first in a new ultraportable pocket line of DAC/amps called the GO Series; now, it's joined by the GO bar, taking the concept of big sound in a small footprint to a whole new level.

Like the GO Blu, the GO bar fits into any pocket, with a robust structure yet made of light metal alloy, measuring 65x22x13mm and weighing just 28.5g. But while the GO blu has the greater convenience of Bluetooth connectivity for devices like smartphones when you're on the go, the GO bar connects to devices via USB and focuses on performance. Whether you're working remotely or at your desk at work, or simply traveling for pleasure, the GO bar is the perfectly portable way to make your headphones sound heavenly when connected to desktop computers, laptops, phones, tablets, or any other digital source device with a USB port.

The GO bar isn't the first USB DAC/headphone amp of such diminutive size, but its specification is second to none. Its hi-res format, compatibility and sonic tuning capabilities are unmatched, and its amplification stage is the most powerful in the world for a headphone amplifier of this size. It's really small but mighty.
