This kind of topology is usually seen in larger and more expensive amplifiers because it’s complex and costs more. Matthew Seed Photographyĭespite its small size, the GO bar’s analog circuitry has a balanced design with symmetrical twin-channel output stage.

The outside of the Go bar has LEDs to indicate the file type and which filters are being used. This makes the GO bar a great choice for subscribers to Tidal’s ‘HiFi Plus’ tier where the Tidal Masters (MQA) music can be found. This means that the complete ‘three unfold’ decoding process is performed internally, as opposed to just the final unfold in the manner of an MQA ‘renderer’. The GO bar can also fully decode hi-res MQA files as used by Tidal. The DAC’s architecture maintains DSD data in true native form, unlike other DACs that convert DSD files to PCM. Hi-res PCM files are supported up to 32-bit/384kHz, alongside DSD64, 128 and 256, and single- and double-speed DXD. iFi’s in-house digital development team programmed the XMOS firmware to optimize the sound quality so that it works perfectly with the Cirrus Logic DAC. This processes the audio data received at the USB input stage. The DAC is fed by a 16-core XMOS microcontroller. The iFi’s GMT (Global Master Timing) precision clock system ensures ultra-low jitter, reducing errors and distortion. The DAC is coupled with a customized digital filter that minimizes pre-echoes and ringing artifacts.

Inside the GO Bar there is a 32-bit Cirrus Logic DAC chipset with advanced multi-bit modulation.
