Dreamnine is right about DNSe 3.0....if you take the time to experiment, you can get outstanding sound out of it, plus save 3 EQ profiles for different earphones. It's why I still have my Q2, even though I mostly have to use it at home because of the hyper-sensitive touchpad controls. Also, the Samsung players are pretty high-powered, as well.
