dell soundmax vs. diamond dt-688
 

Hey guys, want to ask for your valuable opinion on a certain issue. My friend recently picked up a diamond dt-688 soundcard off of ebay that he really likes and was urging me to buy one as well. I currently have a Dell soundmax but im looking for a card that handles six channels and this one doesnt. Am i sacrificing much sound quality if any? Which of these two cards would you personally prefer?
