Nice system Rene. Help us help you though. What direction do you want your system to go in? Faster, cleaner, more transparency, or sweeter, richer and more vibrant? Also, what kind of price range are you talking about? There is no one cable that is all things to all people. However, if we know how much you are willing to spend, and have some idea which direction you want to go, we can make more reliable recommendations.
Cheers,
