Review HiFi-IFAs

The German review website HiFi-IFAs recently published a review of the Earmen TR-AMP, after they published several other Auris Audio and Earmen reviews, such as the Sparrow portable DAC. Next to the unboxing and technical details a lot of listening was done with the TR-AMP by the reviewer Falk Visarius. Thoroughly enjoying the Earmen amp and this is reflected in the rating and conclusion.

“The battery-powered EarMen TR-Amp combines three essential functions for €249: USB DAC, headphone amplifier and preamplifier. For many music lovers, this is a valuable basis for putting together a slim and flexible music system with good headphones and active speakers. Despite the low price, the TR-Amp can easily compete with higher-quality components as a player. A practical little helper for high-quality headphones when traveling. The sound is powerful and well resolved, but free of aggressiveness. The EarMen TR-Amp invites you to relax and listen to music”
