Those very detail oriented fellows at Ars Technica
have set their sights on high end iPod speaker
systems, and there can be only one. The review takes a look at the Apple iPod HiFi, the Altec Lansing inMotion iM7, and the Klipsch iFi.
The review is very in depth, but I don't want to say any more lest I spoil the fun for you (but the iPod HiFi does better than expected).
