Well it might not be overkill in terms of power, but I think this one is more going for aesthetics. The Paragon TW450 from Mustek features a 45-watt amp and has a 5.25-inch dual-coil subwoofer. It stands 38-inches high and comes in a glossy black or white finish.
The main selling factor here is appearance. It’s not the most powerful or best sounding iPod dock out there, but I don’t think it’s aimed at audiophiles (they probably wouldn’t be using an iPod for home audio anyway). It will be available soon for $250 from Mustek.
