Sorry to bother you, but i know practically nothing about Home Cinema Systems, and would appreciate some advice. Is the mx3800 better than the lx3000, why do the on-line retailers e.g. empiredirect, amazon offer the 'lx' range but currys and dixons websites offer the 'mx' model? The MX3800 has 350Watts vs the LX3000's 200Watts does this necessarily mean that it is a better system? Does the fact that the Philips sub is powered mean that it is much better than its competitors passive offerings in the same price range? Any advice is much appreciated. Many thanks.
