Hi,
I have had mine for a year now and it works really good.
In xp it did everything just the way it should as a bit gate to my Grace 902 dac.
In Vista it has some glitsches though. Sound tend to get click noises every now and then, but this is improving as new drivers appears I guess.
A good feature is the unbalanced plus balanced outputs of course.
Sound if you use it as a stand alone player isntĀ“t the best though, but quite allright for that litlle money.
