Sonic Integrity is selling the Tube Pod, a luxury iPod dock that comes with an amplifier. The dock's name stems from the vacuum tubes used in the amplifier, which some audiophiles say produce better sound than transistors. Power output is 13Wx2 and frequency response ranges from 20Hz to 20KHz. Other features include banana plug speaker cables, an auxiliary audio cable for connecting devices like a CD player, and a video cable to display images on a TV. Sonic is offering the dock for the price of $1,000.
