Did a lot of research before buying the topping d30 and am glad to say it has stellar sound quality. I use it for connecting my pc and Mac to my NAD integrated amp on my hifi system since my amplifier does not have a built in DAC like the newer models. The topping is a big improvement over when I used to use the headphone out on my computers to listen to my Music. The dynamics, transparency, and distortion is much better now. Excellent for the price and recommend to anyone who wants to upgrade their DAC.
