If you are looking for a warmer sound then OCOS or Supra would not be the choice IMO.
Cardas good be a good choice depending on the model. I would also consider the Fusion cables as you mentioned. Eric is great to deal with and they do impart a warmer sound. I used to own the Interlocker ICs and Predator power cords.
Another option could be the Stealth PGS (used) or other cables that use gold. Examples include Gabriel Gold and Jade Audio, both of which I have had ein my system.
