If you are unsatisfied with the sound quality of your iPod, then you can use the AT-PHA30i iPod amplifier from Audio-Technica. Scheduled to be released on December 18th, 2009, the device boosts the 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 gadget’s battery life span. It is compatible with iPod nano, iPod Touch 2G, and iPod Classic.
