Hai Karan,
Go ahed with Logi..Z5500. I am using it since 16th Sept.'10 with my Philips DVD Player via coax output. It's sounding great. Bass is simply outstanding because it has 10" sub which produce a excellent bass. It has very good mid range so U can't miss any vocal reproduction. It has five connectivity option (3 analog, 1 optical & 1 coax and has 6 channel direct option for PC audio out)
It is THX certified and has in-built Dolby & DTS decoter. U don't need any seperate amp. Just connect ur several gazets and enjoy a great listning exprience.
My personal rating:
For Movie 09/10
For Music 08/10
Hope it helps U,
Thanks & regards.
