Pros: Warm sounding, 2-headphones output, that are not impedance limited, good value
Cons: Pretty big, can get somewhat warm, the DAC inside is not the best one I've tried.
This is a warm sounding amp and really smooth with enough power to drive 2 headphones simultaneously. As Lan647 was saying that it could drive 2 high end headphones without a problem, I can drive my beyerdynamic t1 & the sennheiser hd800 with ease at the same time. Pretty neat feature if you wan't to compare 2 headphones.
I've compared these with the nuforce icon hdp and it pretty much beats it at every aspect except the nuforce's extra ports and compatibility.
Headphones I tried them with:
Sennheiser HD650, HD8000, Beyerdynamic T1
The hd800 really shined with this AMP, it delivered really deep bass and it really brings out the amazing soundstage the HD800 is capable of.
The inside DAC is nothing special, it produces good sound but I highly recommend buying a separate DAC for this amp.
But in the end its good value for the money you pay for it.
