Good but overpriced.
While this is a pretty good headphone amp there are better deals to be had. It has great mids and highs but the bass is a bit unrefined and not as tight as my much cheaper Fiio K7. Its rather boomy if you know what I mean. They should also offer that super charger power supply as a standard power supply WITH the amp. You should not have to shell out another 3-4 hundred dollars for a modest upgrade. It does have lots of power though in balanced out. In my opinion it is worth maybe half to 2/3 the MSRP.
