Anybody here has a CREATIVE GIGAWORKS S750 7.1 and has been using it for more than  a year it would be wise to check the big capacitors in its Power Supply as it has a tendency to burts thus taking with it several power transistor and the most trouble is it will also take with it some of the power amp ic w/c is very hard to find and this is mostly cause by these cheap CapXon that Creative choose to use.If your handy with soldering it should be easy to replace 4 of them with a good cap like Rubycon.I just service 3 of them and all the trouble are the same blown CapXon cap.

I always thought these expensive PC audio systems were overpriced, theres some proof here.
