It's system dependent. How else would you explain Dolfan's experience when the man who does the mods recommends one thing, and Dolfan experiences better results with another? Certainly Dan is recommending the RAL silver umbilical because he believes it's the best. Dan's too honest a guy to be blowing smoke.
Glai, it's been said hundreds of times in these threads. You have to try the cords in your own system with your own ears. I'd suggest cords from manufacturers who offer MBGs: Revelation Audio Labs, VH Audio, Michael Wolff, SignalCable. You should be able to find an excellent aftermarket cord from one of these guys.
I also agree with the TG Audio 688 suggestion. I personally use one of these cords, though not on my digital source.
