I pass on the Corsair quality: it is ultra strong and even if we like it or not the design "poor" in this kit, after all, AC is not what is asked ...
In terms of audio quality: I just rediscovered some music, my video games, or DVD playback ... A one detail, I find that the mediums are a little too sharp, and corsair should have allowed, since its remote control, setting an acute / serious for these speakers. Another negative point, you can not adjust the balance left from the remote, strange for a kit that price. Indeed, it may not necessarily place the satellites homothetic manner, and suddenly one would like to set the balance easily.
You will need to make these settings from the software that controls the sound on your computer, or from the interface of your sound card (clearly recommended if one wants to enjoy the quality of this kit).
One more point that annoyed me: you can not find anywhere the exact length of satellite cables. Yet it is important to know whether we will be able to install the satellites as we want ... in short, cable too short for me (about 2m). And no luck, Corsair has chosen the ATX cable 4-wire, not very usual for audio ... impossible to find extensions of more than 0.65 m (made for the PC power supply). You will, or by making longer yourself, or cut and weld ... I removed one star again: Mr Corsair, for the price, add at least 2 extensions 1 to 2 meters, AC will not luxury!
