The sound quality is simply outstanding! Very clear and very well restored. I really rediscovered all my titles and I'm not talking about the DVD whose sound has become almost as nice in the movies!
Moreover it must be said, the X-530 have great style and are very pleasant to watch. Each speaker (except the center) has a small hook to attach them to the wall if necessary (still provide good fixation because it is not all light). This is also why (and the subwoofer) and that the packet so heavy! Inside it is very well packed, styrofoam around the subwoofer and the other speakers enclosed in a small box and all surrounded by plastic bags.
In terms of connectivity, the length of the cables is correct, especially for the two rear speakers. In contrast to the front ones I found it a little short because it forced me to put the box (or plugs) directly under my office.
In the package leaflet explains to newbies in 5.1 speakers (like me ^^) how to perform all connections (simple) on the box and then on the sound card. There is also an adapter to connect the consoles like the PS2 and PSX.
So if you are looking for a good 5.1 kit, take you on that one, the price / quality ratio is exceptional (about 20 fewer than on amazon commercially 1/3 the price anyway oO)
