Any Nordost interconnect experts out there?

I have two questions. First......Nordost does not seem to suggest that their product line is designed for a particular purpose. For instance, tube amps vs. solid state vs. turntable. Since I have Red Dawn speaker cable, and I like it, I'm looking at Nordost balanced interconnects to run from CD to preamp, and preamp to tube amp. Any suggestions as to what Nordost interconnects are best for specific purposes? Also.....If you had two interconnects, one good, like Baldur, and one very good, like Tyr, would you put the very good pair from amp to preamp, or from CD player to preamp? Or is that just a dumb idea in the first place :)
