Ballan has a good suggestion and a good point.
Kimber and Cardas are two solid products.
I have found over the years that many cables sound really terrific, and the pool of potentially satisfying possibilities is fairly robust.
I have come to the conclusion that if one is going to shell out large dollars for wire, the safest bet from a standpoint of strong residual value is to buy products that are in constant demand.
If this idea carries any weight with you, then take a look at the classifieds to see which cable companies have a strong list of items for sale, and follow newly listed items to see how long they stay on the market.
Some other options are Shunyata, Analysis Plus, MIT and Kubala-Sosna (no particular recommendation here from me...it's all too predicated on user preference).
