Hi, I've done loads of research on the Kef KHT 2005.3 and am pretty set on them. However I've seen this Brand New Kef KHT 5.1 AV Egg Theatre Speaker System on eBay, also, Home Cinema Systems, DVD Home Cinema, Consumer Electronics (end time 09-Feb-09 21:00:00 GMT) which is quite a bit cheaper (once I've submitted an offer). How do these compare? Are these the same speakers as in the KHT 2005.3 kit? I know the sub is different, is it better, worse? On paper it says it's 250w rather than the 200w on the Kube 2. Any advice? Many thanks in advance.
