The basic distinctive is DSP-based MPEG encoding/decoding, both L2 and (on the 
6000 series) L3.  They sport pro-style interconnects (balanced analog i/o, 
AES3 digital) as well as hardware-based mixing and metering.  The 6000 series 
will also do real-time "no pitch shift" time shifting.  They've supported 
Linux for several years now with their custom "HPI" driver.  The whole 
"properietary driver" approach is common with cards aimed at the broadcast 
sector, with ASI (as well as Digigram and Antex) offering special APIs on M$ 
platforms as well.

All in all, I've found them to be very solid, high-quality cards.  Their HPI 
driver has been top-notch in terms of stability.  A bit on the pricey side,
