I'm going back and forth between the Extigy and Audigy. Ultimately, for what I want it for, the Audigy EX is the best for me (I think).
I'm an amateur muscian and want a decent setup for recording guitar into my computer. My current soundcard (TB Montego) is adequate for getting sound into the computer but by having to use adapters(1/4" to 1/8") to get it into the soundcard, I must be losing something soundwise. Although, having just checked my guitar processor, I do have an s/pdif connection on it. This could open up some other possibilities.
