The specification table rates balanced output at 7.2 V into 600 Ω; the feature text says 7.5 V maximum into 600 Ω. We display the table rating with this discrepancy disclosed; no measurement-mode explanation is supplied.

Is it enough for your headphones?

iFi rates the GO bar at 475 mW into 32 Ω from the 4.4 mm balanced output. Below is how much of that is left to spare for each kind of headphones when you listen loud, with peaks at 110 dB. A figure marked est. is worked out from that rating.
