It's not quite an EQ, it's a proprietary DSP-based exciter/expander. IXBT has more:

It has a dynamic component that an EQ lacks. You can't quite replicate it with just a graphic or para EQ - you can get pretty close, but not 1:1. Just like the BBE Engine; you can get close, but not 100%. Watch Creative back-peddle their marketing claims in their reply to IXBT too! "We never claimed it produces DVD-Audio mastering quality!"

I think where it's "magical claims" is that they didn't just come out and say "dynamic EQ" or "intelligent dynamic EQ" - they put out that "studio quality with X-Fi" trash. I think it's a neat toy, and encourage people to try it (or other exciter/expander effects, like BBE, Pioneer, etc) but have no delusions that it's doing whatever that marketing graphic says.
Another fun one to knock on is high bitrate digital content in general - anyone else read the Xiph post on it? I also used to have this really nice AC-3 vs DTS vs MLP resource, but lost the link; basically there's a lot of magical claims about what silly high bitrate/lossless/etc data gets you, that isn't validated by actual studies or in real world practice.
