It sounds like the leakage current is interacting with the resistance of whatever is connected after. It sounds like you measured DC offset with the amp (or whatever it is, it's not clear) plugged in. It sounds like your amp has no DC blocking caps. If the amp has a potentiometer, it's probably interacting with it. Depending on the potentiometer configuration, the resistance may change depending on the volume control position.
You'll never solve the problem with supercaps. The leakage currents are too high, in the 10s of uA range. "normal" caps used for DC blocking leaks in the nA range. If you put a low value bleeder/pull-down resistor, you'll increase the current load on the ipod's output stage. If you put it too high, nothing changes.
