Our take
This device is great when the output is not totally clean or with a general low quality. It won't do wonders and magically make the signal perfect, but it will make the background cleaner and improve the sound. One of the greatest benefits of using Topping NX1s is being able to apply basic bass equalization make the Topping NX1s worth its price by themselves.
