The Logitech Pure-Fi Express Plus is superb - crisp treble and lovely soundstage for its size.

I don't know why people are dissing it so much. Price-wise it's cheap and compared to the Altec Lansings in the same category has a good deal more precision and clarity.

I used ALAC files for the comparison tests and while the Altecs did give better bass - for a quiet environment and at low volume, the Purefi Express Plus is excellent.

Then again, I only got it to replace my alarm clock...
