probably, since they don't make things like Idocks (for ipods) for creative, you don't have any other option then hooking it up via a analog 3.5mm minijack to stereo rca, and those, as we know, suck,

i hooked up some mp3 players from friends to my amp (well, not now, when they were here, which happens sometimes), and i found they where really boomy and well yeah, too much bass and no treble.
which is logical, since the dac in the mp3 player is cheap, and not really made to be hooked up to a expensive stereo system.
