Are you satisfied with the sound quality of your iPod? If not, maybe you can use the AT-PHA30i iPod amplifier from Audio-Technica. Planned to be released on December 18th, 2009, the device features the iPod’s output power to 20mW (32Ohm) and provides a frequency response of 20Hz-20,000Hz, as well as a signal noise ratio of 95dB. The AT-PHA30i draws its power from the iPod’s battery, so it will decrease your device’s battery life span. The portable amplifier is compatible with iPod nano, iPod Touch 2G, and iPod Classic.
