hmm. I'd look at independent test results before I believe
any such SNR specs. it's possible that they've produced
such a card ...  it's also possible they've fudged the specs.

as for the 2 ms latency... i don't think there's actually any
difference between the cards there, I think they're talking about 
different things.  An input -> output round-trip will 
invariably have some latency,
and 2 ms is pretty close to the hardware limit. The "zero latency"
feature of some "pro" cards means that you can monitor inputs before
they go through the A-D / D-A conversion so you don't hear a
smeary delay on the live parts.  I don't know if the Audigy does
this.
