You know, this is all marketing bluff. Please have a look at this
wikipedia article. From the many things, what they did with the Zen X-Fi is putting the Crystalizer in. As you know, or should know, saying that you can not only recover the 16bit accuracy of a CD, but 24bit accuracy from an MP3, that is a big lie. And Crystalizer is by no means the most processor consuming feature of the Soundblaster X-Fi cards (see 3D sound in multichannel enviroinments), so Crystalizer can be put on any DSP, as far as I can tell (see the low end card that was rebranded as X-Fi, doing the Crystallizer via software).
But giving the brand X-Fi to the Zen, well, that is particullarly confusing. It just does the Crystallizer stuff as far as I know. Ok, maybe some stereo expanding. I wonder if people could not create a device that actively does noise cancellation without requiring extra batteries. That would be a really nice use of a powerful DSP. And not just this marketing stuff.
Call me ranting swede, but damn, I know that even uncompressed audio CDs have noise coming from the mastering process. How can you have 24 bit accuracy if somebody put noise at the 16 bit levels? (The reason for that is that you are likely to like random noise better than quantization noise). Damn, I just hate marketing stunts.
At the end, they just branded X-Fi because of the Crystallizer stuff that is not X-Fi dependant, as they already demoed with that rebranded Audigy card.
"If they got someone up to the moon, how come they could not have left him up there?" - THE ranting swede.
