I Have came across this system at the logitech website, and i was very interested in it because of the reviews. Several months later i had bought it from Alienware.com, when it had arrived i was very impressed with the system. The set up was very simple, it took me about 20 minutes to have it set up and fully running. All wires come precut, which make everything simple.
I bought the Logitech z5500 mainly because i wanted to enhance my movie, music, and video game experience. Movies sound great, the sound is very crisp and the bass hits great with explosions, you will feel like your in the movie yourself. The Xbox 360, and The Playstation 3 Both sound awesome but ofcouse you will need an optical cable to use the 5.1 surround sound. Every single sound in the games sound great, you wont regret it. The music also sounds awesome, very clear and crisp.
Those looking for a sound system should buy the z5500.
