I'm using a 80GB ipod classic (2007 version) without an amp (gave to my friend) and the bass sounds distorted and muddy, like there isn't enough power. Feels like it covers the rest of the sound.
Plugged it into my logitech z5500 control pod, which is connected to my cheapo creative x-fi Extreme Gamer soundcard, and it sounded much better.
Been using rockboxed clip+ as my portable, and haven't used the ipod in a while.
Am I imagining things?
