Fosi Audio K7 Gaming DAC/Amp Review


New K7 Gaming DAC Headphone Amp from Fosi Audio! The Fosi Audio K7 combines the function of a digital-to-analog converter and amplifier in one compact device, so it takes up very little space on your desk. With the AKM AK4493SEQ, it has a powerful off-the-shelf DAC chip and not a discrete solution. The attribute of being geared towards gaming in addition to music is interesting, which predestines it on OCinside.de for a practical test in the localization of sound sources.

Headphones have become an integral part of the world of listening pleasure and magnetostats in particular demand a lot of amplifier power. For this purpose, there are no longer just on-board solutions in computers, but external DAC/amps such as the new K7 from Fosi. This is designed to impress with 2.1 W symmetrical output power, low non-linear distortion and high sampling rates.
