well personnaly I gotta say I have a quite good hear, I've been djing for 5 years and to honestly I can't find much difference between that package and an amp and speakers. Sorry!
Maybe the quality is not exactly as good but saying they are "pretty poor" compared to them is a lie
that made me LOL. no offence but that is ridiculous. I have the Logitech Z2300 and they are good as far as computer speakers. great for games etc... but honestly they are miles away from my Bower & Wilkins. BTW I am no sound expert and can clearly tell the difference between the two even in a blindtest.
