Can someone quantify the differences in the TB Santa Cruz versus run of the 
mill sound cards in real day-day RTTY/PSK QSO's using MMTTY, etc.

Does the Santa Cruz copy 10% better?  20% better?  1 character in 1000 
better?  Or are the differences mostly in the specs and don't show up for 
the most part in regular RTTY/PSK QSOs?
