Abbingdon Music Research GO bar - Ultraportable DAC Headphone Amp

The new addition to the GO series - the GO Bar

Pocketsize Hi-Res USB DAC,Preamp and Headphone Amp

The GO bar is a top-of-the-line USB, ultraportable DAC/headphone amp: Works with PCs, laptops, phones, tablets or any other digital device with a USB port. Most powerful in the world for a headphone amp of this size, with a wider range of headphones than any other ultraportable USB DAC/amplifier

The GO bar combines sonic purity with exceptional power outputs:

475mW into 32 ohms – enough current drive to for 16-ohm headphones

7.2V into 600 ohms – sufficient voltage for 600-ohm headphones

The small, yet mighty GO bar is the world's most powerful headphone amp of its size.

The GO Bar is a balanced USB audio DAC amplifier. The USB-C plug-in plays up to 32-bit/384 kHz, has 2x DXD and has full MQA decoding and native DSD up to DSD256

True Balanced Circuit Design/

The GO bar's analogue circuitry boasts a balanced circuit design with twin-channel output stage. This reduces noise and crosstalk in the signal path by fully separating left and right channels. Remarkably given its diminutive size, the GO bar’s analogue circuitry features balanced design with a symmetrical twin-channel output stage. This topology, usually reserved for larger and more expensive amplifiers owing to its cost and complexity, reduces noise and crosstalk in the signal path by fully separating the left and right channels. Special attention has also been paid to power supply filtering, dramatically reducing signal noise introduced though the USB input. The amp’s design combines sonic purity with exceptional power. In fact, with an output of 550mW (into 64 ohms) and 7.5V (into 600 ohms), no headphone amp of such diminutive size can match its impressive ability to drive even tricky headphone loads – that’s enough current drive for 16-ohm headphones and sufficient voltage drive for 600-ohm headphones.
