Bmdduck, I don't know how old your Echo Gina is but there are new driver updates for these soundcards as of 2007. I have the Echo Layla 24(2003) version and just upgraded my driver yesterday and the sound quality improved quite a bit. The first thing i noticed was overall volume which didn't impress me but then it was seconds later that i realized i was also hearing more dimensionality and seperation too. Highly recommended to download the newer driver which you can find on the Echo website very easily. In fact here is a link- you are going to want the 7.3 at the bottom of the page if you don't already have it:
