Pros: Really Portable, Rich Feature Set, Balanced Soundstage
Cons: With 8.1 some usb issues
+Specification rich, nearly usb size amplifier.
+The most portable real solution I have seen.
+Price point is very good. Hard to beat the price/quality ratio.
+Gamers will like it as much as Hifi heads.
+Generally use it with JVC HARX700 and Grado 80i and really satisfied.
- EQ pre-defined settings are bad. EQ must be developed..Basic Audio Center.
- Not crystal clear output (but very close to it)
Highly recommended for low budget Hifi experience.
