Psyclone lets you treat your Sony PSP as it would be an Apple iPod by offering a Stereo Speaker Dock for the Sony Playstation Portable.

Nodus incorporates Sonic Impact’s Class T Amp Technology. The T Amp utilizes both digital and analog signal processing to maximize all frequencies. The result is powerful, clean, room filling sound.
You can actually play the PSP connected to the Nodus Dock from up to 6 feet away.
Other features include remote control, built-in connector for recharging and playing the PSP and TV-Out.
The Psyclone PSP Sound Solution will be available in November 2006 at major retailers in the United States for $199.
Looks like the company does not have a web site yet.
