Update: I took the CF card that still has the show on it(Kingston 45X 4GB)to work and played it from the card through a Creative Audigy 2 zs and the hiss was there....also transfered to the HD and it was the same(not sure that would have made a difference).
I listened to it through Sony 7506 headphones, I guess it would not be as prominent through shitty HPs.
I am going to go back over the set up of the 671...all the cables are brand new (I know, I know). I am going to record the same band tomorrow(Mary Ann Redmond Band), along with the Nighthawks at the State Theater, maybe I will try another card.
