I purchased one of these a few weeks ago in a sale because it's quite a bit less chunky than others and it has a couple of pre outs which means I can use it with existing 2 channel hifi.
It's a very nice unit, sounds pretty good to my ears and it has the Audyssey calibrator built in and allows for lots of customisable settings. It's only 50W rms per channel so don't expect it to offer earth shattering volume particularly in a bigger room. But it's good value for money, especially with large discounts available.
