Pros: Nice clear transparent DAC sound, warmish amp section that makes everything sound good, nice appearance and build quality
Cons: More power is always welcome
Above is the link to my full review. In summary:
This is a great little USB DAC/amp for the price. Nice clear transparent DAC section paired with a somewhat warm and almost tube-like amp. There are plenty of good options out there in this price range, and the U100 is one of the best I've heard. Worth a try if you want a sub $250 USB DAC and amp combo.
