I’ve enjoyed reading the glowing reviews of the Sonic Impact Class T Amp that generates 10 watts per channel from eight alkaline batteries. You can connect your iPod plus a couple of external speakers to the palm-sized device and have a powerful stereo system that fits just about anywhere… and for cheap! I bought mine for $30 at Amazon.

I haven’t been disappointed with the Sonic’s sound. It produces clear, full-bodied output that’s a perfect complement to your iPod. Connect your music using the included stereo mini plug cord, attach the speakers, and you’re ready to rock.

There are a few minor gotchas, as you would expect from a $30 amp. The batteries are difficult to insert, and the jacks for the traditional speaker wires could be better. I’ve gone into more detail about these and other aspects in my review on TDS. But I have to say, for a $30 investment (plus digging up a couple of two-way speakers out of the closet), you have a heck of a good stereo system for you iPod.
