anyone upgrade from the Logitech Z-560s to the Z-680s ?

[Toothpick]

Hey All
Just wondering as I have had the Logitech Z-560s for about a year now and I am ready to upgrade my speakers so I am seriously thinking about the Logitech
Z-680s, I read some reviews about them and they all said that it is a vast improvment over what I curently use right now

So has anyone done this yet ?

I have the 560's and I say go for the 680's if you have the cash
