I went with the principle "the more, the better" so I ordered The SuperDuper. I intend to use it both at my office connected to a PC and connected to a Android device. I may buy a real high end head phone later. But I don't have, yet. So maybe I am thinking wrong here? Apart from money (no big deal, since it is spent on electronics :-) ) is there a disadvantage to the SuperDuper? Too much power or something like that. The imponator effect is not to be dismissed lightly.
