This appears to be the successor to the IM600, which is still available.
Sound quality is just as good - it will fill a fair-sized room with clear, balanced sound and reasonable bass tone.
The angular, rectangular design with sharp edges looks a bit old-fashioned but is probably more pleasing to the eye than the black slab of its predecessor. The stand which converts to a carry handle (and folds flat when you want to stow it away) is quite a neat idea.
Now the minus points. The little black and amber dot matrix screen scratches and marks far too easily. The angular design means that, when docked, your i-pod stands up proud from the station and feels less well supported. I can envisage strain on the notoriously fragile connecting pins.
Radio reception is very poor, despite having a very long telescopic aerial.
Battery life, at a maximum 3.5 hours, is hardly generous.
Finally, there are no instructions provided, other than a few rudimentary graphics on the box (you can, however, download them from Altec Lansing's website).
In conclusion, the IMT620 Classic sounds good, and looks OK, but build quality and radio sensitivity are poor. For £100 or thereabouts it's not as good as it should be.
