At the outset, I should say I am interested in good quality music playback, rather than surround sound for gaming. I have an old SB Audigy, and would now like to upgrade. I don't have a whole heap of money, but am not sure whether merely swapping for an Audigy 2 of whichever type would make much difference. ie would it be worth saving up for something rather better? Therefore, any suggestions and experiences would be much appreciated!
