M2Tech has taken a leaf out of Audioquest’s book and built a Dragonfly competitor in the highly compact form of the HiFace USB DAC. This asynchronous converter is only 88mm long (3.5inches) yet can decode at up to 32-bit/384kHz and combines a USB plug input with minijack output. It plugs straight into a PC and outputs to medium and high impedance headphones or via a minijack to RCA cable to an amplifier. M2Tech claims it delivers low jitter and low phase noise alongside high stability thanks to a pair of quartz precision oscillators. It does not require drivers with Mac or Linux based computers and there is a free driver for Windows machines. Price will be $295.
