Since you took the time to find the thread and post, I'll play.

My "portable" system is something I can take outside and listen to while I'm cooking on the grill, or while I'm chillin' on the deck and I'm thinking of taking it to a football game for tailgating.

Sonic Impact T-amp (first generation)
Insignia 6.5" speakers
Optimus/Radio Shack portable cdp w/lineout

Admittedly, this system is a little bulky and not too personal, but once it's set up, it rocks. Everybody who comes over loves it. It sounds great and there's something about the combination that really smooths out the sound of cds. Plus, after catching a sale at BestBuy when the Insignias started getting recognition on the web, and finding the cdp on eBay (nos-still in box) for cheap, the whole package was about $90.

I'm looking to add a good battery powered radio.

BTW, welcome!
