Looking between these 2 sets of speakers. Logitech X-530 PC Multimedia Home Theatre Speaker System - 70 Watt (Total) (5.1): Amazon.co.uk: Computers & Accessories Logitech Z323 Speaker System: Amazon.co.uk: Computers & Accessories The latter are not in stock but don't mind waiting. I just want to be able to listen to music a little louder and watch TV shows/films. I wouldn't mind spending 50 quid but would prefer about 40. What else do I need to hook them up to my laptop or do they just go into the headphone jack?
