We like this headphone amplifier a lot. The sound is a wonderfully seductive combination of transparency and grip. From the midrange upwards the Aurium is as detailed as you like. But you'll need a high-quality source component and a first-rate pair of headphones to get the full benefit of its excellent capabilities.

This is a supremely capable headphone amplifier and also a fine, if slightly feature-limited, stereo preamp. And that is enough for the full five stars – treat the built-in DAC as a nice bonus.
