Rather not, because the USB model wasn't yet available back then. So it probably rather was the original ESS-based DMX, the Crystal-based Xfire or more likely (especially if your "from 2002" would refer to the product introduction rather than to when the guy bought/got it) the ICE/VIA-Envy24-based DMX 6fire 24/96 (with the drive-bay module) or the "light" variant thereof, the DMX 6fire LT.
Personally I remember the DMX 6fire 24/96 (and LT) as better sounding than whichever was Creative's current Audigy generation at that time - however, irrc, the 6fire 24/96 relied on purely analogue audio signal transmission between the card and the drive-bay module, while the Audigy would do it digitally, which made Creative's solution more insensitive to PC-internal EM radiation.
