Premium USB DAC. World’s most powerful headphone amp of its size.

A customised digital filter minimises pre-echoes and ringing artefacts. Our GMT (Global Master Timing) precision clock system ensures ultra-low jitter.

• Ultra-res PCM up to 32-bit/384kHz via USB ​
• Native playback up to DSD256​
• 2x DXD​
• Full MQA decoding

Four bespoke digital filtering options:

• Bit Perfect​ – no digital filtering, no pre or post ringing​
• Standard – modest filtering, modest pre and posting ringing​
• Minimum Phase​ – slow roll-off, minimum pre and post ringing​
• Gibbs Transient Optimised – minimum filtering, no pre-ringing and minimum post ringing​

​Two analogue processing modes:

• XBass+  – an analogue bass boost to ‘add back’ lost bass response for more accurate reproduction of the original
• XSpace  – a holographic sound field to open up your music to give you the spaciousness of a live concert

At one end is an asynchronous USB-C input and at the other a pair of headphone outputs.

• 4.4mm fully balanced output – headphones with a balanced cable/connector can benefit from the fully balanced circuitry of the GO bar
• 3.5mm S-Balanced output – our S-Balanced tech cuts crosstalk and noise by 50% with regular single-ended headphones.

The amp’s design combines sonic purity with power.

• • 475mW into 32 ohms​
  • 7.5V into 600 ohms

​No headphone amp of such a diminutive size can match the GO bar’s ability to drive tricky headphone loads or work with a wider variety of headphones.

The GO bar also incorporates two power tuning technologies:

• • iEMatch – attenuates power to suit high-sensitivity headphones and IEMs, it removes background noise and increases usable volume range
  • Turbo – ramps up the gain by 6dB to satisfy more power-hungry headphones
