When comparing expensive cables, it really doesn't make sense to say this or that brand is superior to another--it really is a matter of matching gear to the cable and a matter of personal taste. It appears that the original poster found a good match with the Siltech. In another system, the Nordost might better the Siltech.
There are a few brands that have cables that seem to match a broader range of gear, Siltech and its sister brand (Crystal Cable) being examples of such, while others are more specialized. Nordost cables are on the very fast and detailed, and leaner side compared to other brands in almost every system I've heard them in so they are more limited in the applications where they would work. A brand like NBS has different lines of cables with distinctly different sounds, although their crazy expensive Black Label cable is as close to a univerally good cable as I have ever heard.
In my system, I like the silver Audionote cables (I have a 4-meter run of Sogon between my linestage and amp); this is a cable that delivers clarity and detail without being unduly bright or lean sounding.
