Pros: DAC and amp combo
Cons: Finicky to get around menu's and change things fast.
This is going to be short, It does everything it needs too with a good DAC and many features. Some of my headphone's need quick EQ'ing or navigation and this is pretty finicky. It is a solid device but there is some quality problems such as a rattle that seems to be attributed to the LO Bypass switch and also some..not as tightly made spots you spot every now and then. This may not be the greatest amp for $150 or greatest DAC for $150...but guess what? It does them both with extra features and what not for such a price :)
