Pros: Amazing for the price
Cons: Gain has to be changed internally
Amazing headphone amp for the price. Used with my 325is, Pro900s and Q701s. Great value, drives most headphones incredibly well, even powered my Q701s on the high gain setting with no signs of distortion. It's a really nice looking headphone amp for the money also, very study with a neat, clean build. For the price this absolutely can't be beat.
