To what i understand till now, getting bass out of songs is more about the headphones than The Source. ya, if u have high impedance phones and a low power source, there sure would be a problem, but otherwise, with normal impedance, in the range of 32-64 ohms, a player like the Clip or the Clip+ can provide u with enough bass....infact, imo, the low frequencies on the Clip are pretty extended, so that shouldnt be a problem.
