iFi

Quick answer: The one to buy from iFi here is the GO bar — a 475mW portable USB DAC/amp with a 4.4mm balanced output that turns any phone or laptop into a proper source. It has enough power for demanding IEMs and most full-size headphones on the go.

iFi Audio designs in the UK and takes a distinctly engineering-led approach: proprietary filters, careful power supply design, and features like IEMatch that solve real problems (hiss on sensitive IEMs) rather than chase spec sheets.

The portable line is a favourite among listeners who want desktop-grade sound out of a pocket device.
