The link you gave directs to SB Live! 5.1 Platinum, not Audigy.
The model is grossly out of date now having been superseded firstly by Audigy and now Audigy 2.
There is nothing wrong with the SB Live! 5.1 system but would you want to wait that time (don't believe the 99 days part - no doubt it will be longer) for a product which is obsolete even at the time you place the order?
