One Super high end cable or mid level set?

Has anybody out of choice decided to allocate all of their cable budget on one super high end model (say for just as an example a Nordost Vallhalla or Odin interconnect) whilst keeping there other cables at a much cheaper range or evan stock.
As opposed to the presumable much more common practice of buying a more 'balanced' mid level but complete cable loom ( again just as an example Nordost Red Dawn)
I suppose the question is can an 'incredible' never to be upgraded single cable produce a more magical ( or even equal) sound ,( supposing of course that it is of suitable quality to reveal these qualities.) than the compromised but more balanced set?
