Tested very briefly and reboxed.


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
External affairs
The GO bar's smart alloy case sports physical buttons for precise volume adjustment plus controls to select between various sonic tuning options. A column of coloured LEDs provides a handy guide to the format and sample rate of the digital audio currently playing, and whether XBass+ and/or XSpace are engaged.
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 - S-Balanced tech cuts crosstalk and noise by 50% with regular single-ended headphones.
