Hello ,i'm new ,so little quick preview on me,i'm a student in video editing and was thinkig to buy a sound card for my educational perposes. I need to know if there is a diffrence in the audio chip between this too cards ,exept the feauters. I need detal exemination of the feauters of this 2 cards. There is another version of delta series i was looking,delta 44 ,the difference from 66 is that it has no digital I/O and it has 4 analog only. I only found out that delta 44 uses VIA ENVY24 audio chipset,don't know anything bout audiophile 192 chipset or maybe delta 66 uses another chipset?...any thoughts?
