I had a demo recently of a top-end iPod speaker solution from a Famous Manufacturer with a four-letter name, which carries what may also be charitably described as a 'four-letter price tag'. This product rivals it in terms of sound quality, beats it in terms of utility, and pummels it into the ground in terms of price.
The iStation is astonishingly light, stylish, and versatile. The surround processor is a revelation, the input options are comprehensive, and the array of cabling which is generously bundled with the unit is a real bonus. The ability to power the unit with AA batteries where no power supply is available is a great idea too. Add to this the fact that the dock recharges your iPod into the bargain, and I'm struggling to think what else you'd want a pair of external speakers to do. Don't concern yourself re. changing the base plate to the one which corresponds to your model -- it's a doddle, somehow managing to be easy to prise out, yet solid as a rock when fitted at the same time.
Good looks and functionality aside, the sound this unit cranks out is clear, balanced, and surprisingly loud, and I'd recommend it on this basis alone.
It you own an iPod and are looking to fill a hotel room, study or bedroom with your music, look no further. There are legions of folk whose main stereo will sound worse than this, believe me.
Buy it and enjoy it.
