if you just like the logic7 - forget any other konfig's. the hifi-system is much worse and there is no comment to the basic system .... in my opinion the logic7 has the active speakers only. if the sound quality is not so important to you, check all the three systems (non hifi, hifi, logic7). i think the sound of each system is better than my english - sorry for that
so long & a good choice, X5
p.s. if you like bass in a very good quality - then take the logic7 and nothing else.
