Sounds great. I have to listen carefully but there is an improvement. It might be a placebo effect! Try it for yourself.
With so many no name and knock off items on the internet, it can become difficult finding a quality item at a fair price. For me, the iFi Go Link fills the need quite nicely. I mainly use the Go Link with my smartphone or tablet. I generally use the Grado SR325x or Periodic Audio Magnesium with this dongle. This combo sounds nice and is plenty powerful. I feel confident in suggesting the Go Link to others.
