The amplifier and DAC combo sound great, all the details and nuances in songs is really brought out. Whether it be headphones or speakers this unit will deliver audio quality with no distortion and no noise floor. The only issue I’ve had with my unit is it does not like to connect to phones directly using type c to type c. sometimes the audio will play other times it keeps pausing and refuses to play. Every other method works fine including Bluetooth, optical, and USB c connected to a windows computer.
